Question

Which statement correctly describes the difference between cellular respiration and photosynthesis?

Answer 1

Answer:

E. Photosynthesis is an anabolic reaction, and cellular respiration is a catabolic reaction.

Explanation:

Anabolic or endergonic reaction is a type of reaction that uses energy.  In this type of reaction small, simple molecules join to make larger complex molecules. For example photosynthesis, during which carbon dioxide and water are react to synthesise glucose and oxygen.

Catabolic or exergonic reaction is a type of reaction that gives energy. in this reaction  large molecules are broken down into smaller ones. For example respiration, during which glucose in presence of oxygen is broken into carbon dioxide and water.  

Answer 2

Answer: Option ' E' is correct.

Explanation:

Photosynthesis is an anabolic reaction whereas cellular respiration is a catabolic reaction.

Cellular respiration is called as catabolic because in this process energy is formed in any form by fragmenting  the molecules into smaller ones. like glucose is broken down into carbon dioxide and water.

Whereas photosynthesis is an anabolic because in this process compounds are formed like it tales carbon dioxide and water to form glucose.

Hence , option 'E' is correct.
