Question

Which process made an increase in chemical energy for cell activities in organisms living on the earth possible

Answer 1

Answer: Cellular respiration

Explanation:

In the presence of oxygen glucose is oxidised through a series of enzyme coordinated reactions to produce energy which is stored in form of ATP.

Answer 2

Metabolism is the process that is responsible for an increase in chemical energy for cell activities in organisms living on the earth possible.

Explanation:

Metabolism is the set of the chemical reactions that occurs in the living cells. All the living organisms needs some energy for growth and reproduction. Metabolism is the process that continues the chemical process in the organisms and activates the organisms to convert the chemical energy that stored in the molecules into other form of energy which can be used for the cellular process.
