Answer:
B. It is the primary molecule in which cells store and use energy.
Explanation:
ATP (adenosine triphosphate) is an energy-carrying molecule found in the cells of all living organisms. It provides the energy necessary for many functions, such as muscle contraction, nerve impulse propagation, chemical processes, etc. It consists of three main structures:
- the nitrogenous base called adenine
- the sugar called ribose
- a chain of three phosphate groups bound to ribose. This phosphate chain is the source of energy the cell uses.
Key is to Lock as Substrate is to Enzyme
A substrate is a necessary component for an enzyme to become active. It is a specific shape that fits perfectly into an Active Site on the enzyme.
Answer:
There is no diagram but
It would be A if you were looking at the endoplasmic reticulum (ER).
It would be B if you were looking at a mitochondrion.
I do not remember what C is, so if it is not the ER, Golgi apparatus, or the mitochondrion, it is most likely C.
It would be D if you were looking at a Golgi apparatus
