Answer: Option D) cofactor that is an activator of the enzyme.
Explanation:
A cofactor is a non-organic component (usually a metal) of an enzyme or protein, that enhances its function. Good examples of Cofactors include iron in hemoglobin, zinc in carboxypeptidase.
Zinc at the active site of the enzyme, carboxypeptidase helps it in cleaving off aromatic amino acids.
Answer:
A. They eat nitrogen-containing compounds found in the soil.
Explanation:
Animals get the nitrogen they need by eating plants or other animals that contain nitrogen. When organisms die, their bodies decompose bringing the nitrogen into soil on land or into ocean water. Bacteria alter the nitrogen into a form that plants are able to use.
Answer:
It helps repair and build your body's tissues, allows metabolic reactions to take place and coordinates bodily functions.
Explanation:
Answer:
Explanation:
When you are thirsty, it's your body's way of telling you to drink some water because you are dehydrated. Just like a dehydration reaction, you've lost water. Dehydration reactions are named as such because as the polymers are linked together, a molecule of water is released. This happens because on one end of a monomer is a hydrogen atom (-H) that is just waiting to bind with a hydroxyl group (-OH) on another monomer. Hydroysis which is the reverse of dehydration work the same way.
Phospholipids are amphipathic molecules. This means that they have a hydrophilic, polar phosphate head and two hydrophobic fatty acid tails. These components of the phospholipids cause them to orientate themselves, so the phosphate head can interact with water and the fatty acid tails can't, hence forming a bilayer.
Macromolecules are large structures composed of atoms and smaller molecular structures and play important and sometimes vital roles in creating and sustaining life. It can be organized into four categories: proteins, nucleic acids, carbohydrates, and lipids.
Carbohydrates:
Found in many energy-providing foods, carbohydrates help the nervous system, muscles, and body in general function. A group of polymers, they contain nothing but carbon, hydrogen, and oxygen. Human bodies break down carbohydrates into their base components, which it then uses to fuel cells and maintain body processes. Plants use carbohydrates, particularly cellulose, to protect their cells and to grow larger. The list of carbohydrates is extensive and includes all sugars and starches.
