Alisiya [41]3 years ago
8 0
Enzymes are protein molecules which serve as catalysts for chemical reactions. A catalyst is a substance which will decrease the activation energy for a reaction. ..... Enzymes will make reactions occur much more easily , quickly and more efficiently than they ever would without the enzyme .

For each moleule of glucose that is metabolized by glycolysis and the citric acid cycle, what is the total number of NADH + FADH
vesna_86 [32]

Answer:

The answer is B- 12

Explanation:

The glycolysis of one glucose molecule produces two acetyl CoA molecules, the reactions in the glycolytic pathway and citric acid cycle produce six CO2 molecules, ten (10) NADH molecules, and two (2) FADH2 molecules per glucose molecule. Therefore the total number of NADH + FADH2 molecules produced is 12.

The absence of which of these will not affect photosynthesis is - oxygen, Carbon dioxide, water, Chlorophyll, light. Give reason
In-s [12.5K]

Answer:

Oxygen

Explanation:

Oxygen is the by product of photolysis during photosynthesis whereby water molecules are split to form protons (H+ ions), electrons and oxygen (by product).

Oxygen is not needed during any of the reactions in photosynthesis and Calvin cycle and will not affect the rate of photosynthesis or possibility of photosynthesis occurring. However, it will affect the process of aerobic respiration instead.

Carbon dioxide is needed in carbon fixation during the Calvin cycle. Without it, 6 carbon sugars cannot be formed.

Water is needed for photolysis to produce protons (maintain the electrochemical gradient) and electrons (to replenish lost electrons)

Chlorophyll are pigments that harvest light energy to excite electrons produced from photolysis of water to be passed down the electron transport chain.

Light is needed as a source of energy to energise the electrons
