What characteristic of carbon allows it to be the foundation for a diverse number of durable molecules?
Carbon has the capability to form four covalent bonds due to the structure of its electron orbitals.
Which is a characteristic of carbohydrates?
The common attributes of carbohydrates are that they contain only the elements carbon, hydrogen and oxygen, and that their combustion will yield carbon dioxide plus one or more molecules of Water.
Which of the following functions can be attributed to carbohydrates?
There are five primary functions of carbohydrates in the human body. They are energy production, energy storage, building macromolecules, sparing protein, and assisting in lipid metabolism.
Which of the following carbohydrates is used to store energy in animal cells?
Answer and Explanation: The carbohydrate used to store energy in animal cells is: (d) glycogen. Glycogen is a polymer of glucose.
Why is carbon the ideal backbone?
The carbon atom has unique properties that allow it to form covalent bonds to as many as four different atoms, making this versatile element ideal to serve as the basic structural component, or “backbone,” of the macromolecules.
Why is carbon considered the backbone of life?
Why is carbon so basic to life? The reason is carbon's ability to form stable bonds with many elements, including itself. This property allows carbon to form a huge variety of very large and complex molecules.
What are the structural characteristics of carbohydrates?
Structure of Carbohydrates Carbohydrates consist of carbon, hydrogen, and oxygen. The general empirical structure for carbohydrates is (CH2O)n. They are organic compounds organized in the form of aldehydes or ketones with multiple hydroxyl groups coming off the carbon chain.
What are the characteristics and functions of carbohydrates?
Carbohydrates have six major functions within the body:
- Providing energy and regulation of blood glucose.
- Sparing the use of proteins for energy.
- Breakdown of fatty acids and preventing ketosis.
- Biological recognition processes.
- Flavor and Sweeteners.
- Dietary fiber.
Why are carbohydrates excellent sources of energy for organisms?
Through many processes, the mitochondria breaks down the sugar in Carbohydrates to make the energy that powers out body. In the end the simple answer is that the carbohydrates are the easiest form of nutrition for our bodies to metabolize and therefore is an excellent source of energy.
Why are carbohydrates important molecules for energy storage?
Dietary carbohydrates provide glucose that body cells can use for energy. Excess glucose beyond what the body needs for immediate energy is converted into glycogen, a storage form of carbohydrate, or converted into fat and stored in body fat cells. Glucose provides energy for all body cells.
What carbohydrates is used to store long term energy in plant cells?
Plants store carbohydrates in long polysaccharides chains called starch, while animals store carbohydrates as the molecule glycogen. These large polysaccharides contain many chemical bonds and therefore store a lot of chemical energy.
Why is carbon a good backbone for organic molecules?
The carbon atom has unique properties that allow it to form covalent bonds to as many as four different atoms, making this versatile element ideal to serve as the basic structural component, or “backbone,” of the macromolecules.
Why is carbon a good backbone for macromolecules?
Because a C atom can form covalent bonds to as many as four other atoms, it's well suited to form the basic skeleton, or “backbone,” of a macromolecule.
Why can carbon form so many structurally and functionally diverse molecules?
Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms, and because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules.
What is the characteristic of carbon atoms that most contributes to its importance to biological molecules?
The unique properties of carbon make it a central part of biological molecules. With four valence electrons, carbon can covalently bond to oxygen, hydrogen, and nitrogen to form the many molecules important for cellular function. Carbon and hydrogen can form either hydrocarbon chains or rings.
How does the structure of carbohydrates relate to its function?
Explanation: Carbohydrates are organic molecules ONLY composed of carbon, hydrogen, and oxygen molecules. So, their structure would be just covalent bonds between the three elements, and most likely non-polar. They give out a lot of energy, and carbohydrates are also known as sugars.
Which is a characteristic of refined carbohydrates?
Refined carbs are primarily made up of sugary starches and glucose while complex carbs have extra minerals, nutrients, and fibers. Because refined carbs have simpler structures, the body can digest and absorb them more quickly.
Which of the following is the major function of carbohydrates structural framework storage energy production?
5) Which of the following are the major functions of Carbohydrates? Sol: (d) Both Storage and structural framework.
Why are carbohydrates considered excellent energy storage for the body what makes them different from lipids?
Lipid molecules contain more energy per gram than carbohydrates (about twice as much) Carbohydrates are more readily digested than lipids and release their energy more rapidly. Monosaccharides and disaccharides are water soluble and easier to transport to and from storage sites than lipids.
Why is it important to eat carbohydrates which provide organic carbons?
Carbohydrates are of special importance because they are direct products of photosynthesis and are therefore the primary energy storage compounds and the basic organic substances from which most other organic compounds found in plants are synthesized.
Which type of organic molecule is the most advantageous for energy storage Why?
Fats (lipids) Fats are the primary long-term energy storage molecules of the body. Fats are very compact and light weight, so they are an efficient way to store excess energy.
Why do plants use carbohydrates to store their energy?
Plants that have leaves or similar leaflike structures use carbohydrates to store their energy during their lifespan. This is because of the two reactions that are producing ATP in the chlorophyl of the leaves of the plant. These two reactions are photosynthesis and cellular respiration.
Which type of molecule do plants use to store most of their energy?
The molecule that plant cells use for long-term energy storage is starch. Starch is a polysaccharide, meaning it is polymer of many sugar molecules…
Why is carbon the backbone?
The carbon atom has unique properties that allow it to form covalent bonds to as many as four different atoms, making this versatile element ideal to serve as the basic structural component, or “backbone,” of the macromolecules.
How does carbon form a diverse group of molecules?
Each carbon atom can bind to another one producing a carbon skeleton that can be straight, branched, or ring shaped. The same numbers and types of atoms may bond together in different ways to yield different molecules called isomers.
Why is carbon called the backbone of molecules?
The carbon atom has unique properties that allow it to form covalent bonds to as many as four different atoms, making this versatile element ideal to serve as the basic structural component, or “backbone,” of the macromolecules.
Why is carbon called the backbone?
Because a C atom can form covalent bonds to as many as four other atoms, it's well suited to form the basic skeleton, or “backbone,” of a macromolecule.
Why does carbon provide a backbone and many molecules?
The bonding properties of carbon Perhaps more important, however, is carbon's capacity for covalent bonding. Because a C atom can form covalent bonds to as many as four other atoms, it's well suited to form the basic skeleton, or “backbone,” of a macromolecule.
Why is carbon the backbone of life?
Why is carbon so basic to life? The reason is carbon's ability to form stable bonds with many elements, including itself. This property allows carbon to form a huge variety of very large and complex molecules. In fact, there are nearly 10 million carbon-based compounds in living things!
