What can we infer if we see a large number of mitochondria in a cell quizlet?
What can we infer if we see a large number of mitochondria in a cell? The cell builds a lot of cholesterol. The cell packages a great deal of proteins for secretion.
Which of the following is a function of the rough endoplasmic reticulum quizlet?
Which of the following is a function of the rough endoplasmic reticulum? The rough ER synthesizes all proteins secreted from the cell; it also functions as the cell's "membrane factory" because integral proteins and phospholipids that form part of all cellular membranes are manufactured there.
How does the function of the central vacuole in plant cells differ from the function of vacuoles in animal cells?
A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the plant cell.
How do chloroplasts and mitochondria function in the capture and release of energy within a cell?
In a plant cell, chloroplast makes sugar during the process of photosynthesis converting light energy into chemical energy stored in glucose. In mitochondria, through the process of cellular respiration breaks down sugar into energy that plant cells can use to live and grow.
What process is indicated by C?
What process is indicated by C? exocytosis of secreted proteins. The event indicated by C includes the fusion of a secretory vesiclel with the plasma membrane and the subsequent release of the vesicle contents to the extracelluar space.
How is the rough endoplasmic reticulum related to the Golgi complex in terms of function?
The Golgi apparatus receives proteins and lipids (fats) from the rough endoplasmic reticulum. It modifies some of them and sorts, concentrates and packs them into sealed droplets called vesicles.
Which of the following is an inference that can be made about a cell that contains large numbers of mitochondria?
If we see a large number of mitochondria in a cell, we can infer that the cell has a great metabolic demand. A high metabolic demand means that the cell requires a large amount of energy released in the process called cellular respiration. The mitochondria are where most of the energy of the cell is made.
What is Golgi apparatus quizlet?
Golgi Apparatus. An organelle in eukaryotic cells consisting of stacks of membranous sacs that modify, store, and ship products of the endoplasmic reticulum.
What is the function of the central vacuole in plant cells?
Filling this space is an organelle called a central vacuole which is full of water. Bounded by a single membrane, this organelle functions as a combination of reservoir, waste dump, storage region and even as a means of keeping the cell in shape.
What is the unique function of central vacuoles in a plant cell?
The central vacuole contains cell sap that is surrounded by a single layer membrane called the tonoplast. The central vacuole's main function is to maintain turgor pressure within the plant cell. This helps the plant cell to maintain its shape.
How does photosynthesis transform solar energy into the chemical energy of sugar molecules?
In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process.
Which types of organisms perform cellular respiration to release energy stored in glucose and other nutrients?
Two Types of Organisms There are two main types of organisms that use cellular respiration: autotrophs and heterotrophs.
Which specific protein structure is indicated by the letter c?
What process is indicated by C? exocytosis of secreted proteins. The event indicated by C includes the fusion of a secretory vesiclel with the plasma membrane and the subsequent release of the vesicle contents to the extracelluar space.
Are mitochondria always the same shape?
Mitochondria may have a number of different shapes. A mitochondrion contains outer and inner membranes composed of phospholipid bilayers and proteins. The two membranes have different properties.
Why is Golgi apparatus called Golgi apparatus?
A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell. Named after its discoverer, Camillo Golgi, the Golgi body appears as a series of stacked membranes.
What is the structure and function of the Golgi apparatus?
The Golgi apparatus is a central intracellular membrane-bound organelle with key functions in trafficking, processing, and sorting of newly synthesized membrane and secretory proteins and lipids. To best perform these functions, Golgi membranes form a unique stacked structure.
How many membranes are present in mitochondria give the characteristic features of these membranes What is the advantage of such features?
What is the advantage of such features? Mitochondria have two membranes. The outer membrane is very porous, while the inner membrane is deeply folded. Porous membrane helps in getting oxygen and food, while the folds create a large surface area for ATP generating chemical reactions.
What is Golgi apparatus do?
(GOL-jee A-puh-RA-tus) A stack of small flat sacs formed by membranes inside the cell's cytoplasm (gel-like fluid). The Golgi apparatus prepares proteins and lipid (fat) molecules for use in other places inside and outside the cell. The Golgi apparatus is a cell organelle. Also called Golgi body and Golgi complex.
Do you remember what the function of Golgi apparatus is quizlet?
The Golgi apparatus is responsible for transporting, modifying, and packaging proteins and lipids into vesicles for delivery to targeted destinations.
What is the structure of central vacuole?
The central vacuole is a membrane-bound organelle containing water and other enzymes that function during the life of the plant. Structurally, the central vacuole is surrounded by a phospholipid bilayer. Phospholipids are molecules with a head and tail that form the majority of membranes in our body.
What does central vacuole mean?
The central vacuole is a large vacuole found inside of plant cells. A vacuole is a sphere filled with fluid and molecules inside a cell. The central vacuole stores water and maintains turgor pressure in a plant cell.
What substance produced during photosynthesis provides food for plants and animals in a food web?
Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.
How does plants and other chlorophyll bearing organisms produce food for themselves?
Green plants have the ability to make their own food. They do this through a process called photosynthesis, which uses a green pigment called chlorophyll. A pigment is a molecule that has a particular color and can absorb light at different wavelengths, depending on the color.
How are photosynthesis and cellular respiration related Brainly?
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide.
Which property of life is exemplified by the process called photosynthesis from which plants produce their own food?
Most autotrophs use a process called photosynthesis to make their food. In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose.
What is the C-terminus of a protein?
The C-terminus (also known as the carboxyl-terminus, carboxy-terminus, C-terminal tail, C-terminal end, or COOH-terminus) is the end of an amino acid chain (protein or polypeptide), terminated by a free carboxyl group (-COOH).
What is the stiff outer coating of plant fungi and bacteria cells?
Cell wall A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid.
What is the difference between active and passive transport across the plasma membrane?
Active transport is defined as the movement of molecules across the cell membrane by using cellular energy. Passive transport is the movement of molecules across the membrane without the use of ATP. No cellular energy is required in this process.
