Answer:
The Calvin cycle uses CO2 and the energy temporarily stored in ATP and NADPH to make the sugar glucose. Photosynthesis is a two stage process. As is depicted here, the energy from sunlight is needed to start photosynthesis. The initial stage is called the light reactions as they occur only in the presence of light
Answer:
d)Its shape determines the neurotransmitters that can reach its active center where activation energy is lowered
Explanation:
Acetylcholinesterase also referred to as AChE, is an enzyme that catalyzes the breakdown of acetylcholine and some other choline esters in the body and this is achieved by breaking down the acetylcholine into its two component parts, acetic acid and choline.
A careful look at the chemical structure of acetylcholine and epinephrine shows differences in the chemical group present and therefore acetylcholinesterase cannot catalyze the break down of epinephrine.
Your best answer is C. catalyst can reduce the amount of energy needed for a chemical reaction to take place.
