Answer:
11) A. The optimum pH of an enzyme is 6.6
12) C. A control group
Energy is the ability to do work which is stored in the body inform of ATP (adenosine triphosphate). ATP is comprised of a base Adenine, a ribose sugar (5 carbon sugar) and three phosphate groups. when a bond is broken energy is released and when a bond is formed energy is stored. ATP is used by cells as a source of energy such that ATP can easily release or store energy by breaking the chemical bonds and reforming the bonds between its phosphate group. The correct answer is c, phosphate- phosphate bond
In terms of environmental economics, the only factions that disagree with one another are environmentalists and economists.
This is false.
Answer:
If the shape of an enzyme changes then the enzyme will no longer be able to perform its function.
Enzymes can be described as bio-catalysts which usually speed up a chemical reaction. Each enzyme has a particular substrate which fits into the active site of the enzyme. Every enzyme needs a particular temperature and pH for its functioning. If the shape of an enzyme changes, then it will no longer be able to perform its function and will become denatured.
