What role do enzymes play in cellular respiration?

Answer 1

Enzymes act as catalysts for biochemical reactions. Only few enzymes are involved in photosynthesis and their role is to enable the process of transformation of carbon dioxide in the air and water to carbohydrates and oxygen.

Answer 2

An enzyme is a (protein) organic catalyst that causes a reaction to occur which would not normally occur under those conditions.

They are required in many biological reactions, including respiration & photosynthesis,

but they don't require either.

Answer 3

The formation of NADH is an enzyme catalyzed reaction. The enzyme brings the substrate and NAD+ into proximity of one another. Through a redox reaction, a hydrogen atom and an electron are transferred to NAD+, reducing it to NADH. NADH then carries the electrons and hydrogen to a later step in oxidative respiration.

Answer 4

They totally control all of the biochemical reactions - one reaction per enzyme - that in turn control all of the processes of photosynthesis, respiration, and many more cellular processes such as reproduction and growth.

Answer 5

In photosynthesis, light energy is used in order to make organic food molecules for plants to eat. In cellular respiration, glucose is converted into energy (ATP) so the human body can function properly.

Answer 6

Most of the reactions are enzymatic, otherwise most of the energy would be used keeping the reaction going, and that would be terribly inefficient. To put it simply, enzymes decrease the activation energy for reactions by providing a place for the reaction to take place to make it easier.

Answer 7

Enzymes act as catalysts in cellular respiration.

Answer 8

to increase cemical reaction in the cell to speed up the prosscess of photsynthesis in a cell of the plants and to store waste products in the plant.

Answer 9

They speed up the chemical reactions in cells there far speeding up resperation, i have the same HW as u!
