What is the function of the organelle indicated by B?
What is the function of the organelle indicated by B? The Golgi apparatus within the endomembrane system functions in the sorting and modifying of membrane- bound proteins being transported to various cellular locations.
What major function occurs on the specific membranes indicated by a?
What major function occurs on the specific membranes indicated by A? Structure A is the rough endoplasmic reticulum (ER). The figure illustrates how proteins are synthesized on ribosomes bound to the rough ER, sorted in the Golgi, and delivered to the plasma membrane for secretion or packaged into lysosomes.
What does the small circular structure indicated by the C represent?
What does the small circular structure indicated by the letter C represent? The mitochondria each have a small circular DNA chromosome that contains genes for several mitochondrial proteins. These proteins are translated within the mitochondria (on the ribosomes indicated by the small red dots).
What does passive membrane transport processes include?
Passive membrane transport processes include simple diffusion, facilitated diffusion and osmosis.
What is the specific role of the enzyme indicated by B during the formation of the new DNA strands?
What is the specific role of the enzyme indicated by B during the formation of the new DNA strands? DNA polymerase catalyzes formation of bonds between sugar groups and phosphate groups that link the DNA nucleotides together.
What process allows for the production of molecule B from a template consisting of molecule A?
What process allows for the production of molecule B from a template consisting of molecule A? Transcription is the synthesis of RNA using DNA as a template.
What organelle is indicated by the letter c what cellular process occurs here?
What organelle is indicated by the letter c what cellular process occurs here? The event indicated by C includes the fusion of a secretory vesicle with the plasma membrane and the subsequent release of the vesicle contents to the extracellular space.
What is the process of passive transport?
Passive transport is a naturally occurring phenomenon and does not require the cell to expend energy to accomplish the movement. In passive transport, substances move from an area of higher concentration to an area of lower concentration in a process called diffusion.
What is active process and passive process?
Active transport requires energy for the movement of molecules whereas passive transport does not require energy for the movement of molecules. In active transport, the molecules move against the concentration gradient whereas in passive transport, the molecules move along the concentration gradient.
What is genetic material at B?
It is known as DNA (deoxyribonucleic acid) or RNA (ribonucleic acid).
What process allows for the production of molecule be from a template consisting of molecule a quizlet?
What process allows for the production of molecule B from a template consisting of molecule A? Transcription is the synthesis of RNA using DNA as a template.
What are the cellular processes?
Cellular processes, such as transcription, DNA replication, and DNA repair, are regulated by an intimate and self-reinforcing crosstalk and interdependence between histone-modifying complexes and other histone-modifying activities, such as acetylation, phosphorylation, and methylation.
Which cellular process is shown below?
(C) Translation – Elongation is the correct answer. Cellular process Translation – Elongation is shown below.
What type of diffusion is passive transport?
There are three main types of passive transport: Simple diffusion – movement of small or lipophilic molecules (e.g. O2, CO2, etc.) Osmosis – movement of water molecules (dependent on solute concentrations) Facilitated diffusion – movement of large or charged molecules via membrane proteins (e.g. ions, sucrose, etc.)
Is diffusion a passive or an active process?
Diffusion is a passive process of transport. A single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across the space. You are familiar with diffusion of substances through the air.
Is diffusion active or passive?
passive Diffusion is a passive process of transport. A single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across the space. You are familiar with diffusion of substances through the air.
Is exocytosis active or passive?
Exocytosis describes the process of vesicles fusing with the plasma membrane and releasing their contents to the outside of the cell. Both endocytosis and exocytosis are active transport processes.
Where is B form DNA found?
DNA is usually found in the B form under physiological conditions. Sometimes kinks are found in the B helix at transcriptional control regions. These kinks can either be intrinsic to the DNA sequence or caused by transcription factor binding.
What process allows for the production of molecule B from a template?
What process allows for the production of molecule B from a template consisting of molecule A? Transcription is the synthesis of RNA using DNA as a template.
What is a function of the enzyme indicated by structure B?
What is the specific role of the enzyme indicated by B during the formation of the new DNA strands? DNA polymerase catalyzes formation of bonds between sugar groups and phosphate groups that link the DNA nucleotides together.
What are the three cellular processes?
The three processes of ATP production include glycolysis, the tricarboxylic acid cycle, and oxidative phosphorylation. In eukaryotic cells the latter two processes occur within mitochondria.
Which cellular process is shown below a DNA replication b translation initiation?
(C) Translation – Elongation is the correct answer. Cellular process Translation – Elongation is shown below.
What is the process of passive diffusion?
Passive diffusion is the process by which molecules diffuse from a region of higher concentration to a region of lower concentration. It is the most important mechanism for passage of drugs through membranes.
What type of transport is diffusion?
Diffusion is a passive process of transport. A single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across the space. You are familiar with diffusion of substances through the air.
What type of diffusion is active transport?
Unlike passive diffusion (and even facilitated diffusion) where molecules move down a concentration gradient, active transport involves the movement of molecules against the concentration gradient.
What kind of transport is diffusion?
passive process Diffusion is a passive process of transport. A single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across the space. You are familiar with diffusion of substances through the air.
Why does diffusion occur?
Diffusion happens because gases and liquids move from place to place in quick random motions. When this happens, the particles collide, which in turn makes them change directions. The process of diffusion occurs on its own without any help from shaking or stirring.
What is exocytosis process?
Exocytosis is the last step of the secretory pathway and it involves the fusion of vesicles with the plasma membrane, a process that, in fungi, ensures the delivery of cell wall-synthesizing enzymes, membrane proteins, and lipids in areas of active growth.
What type of cell transport is exocytosis?
Exocytosis is the process of transporting materials out of the cell in vesicles. It's how cells get rid of their trash and waste material. It is a kind of active transport, so it requires energy input in the form of ATP.
What is the B form of DNA?
B-DNA is the term given for the canonical right-handed DNA helix that is the most common form of DNA. Canonical B-DNA is a double helix made of two antiparallel strands that are held together via hydrogen bonding in the A•T and G•C base pairs (fig. 1).
