Question

Which of the following is incorrect 1.Catabolism involves degradative reactions and includes cell respiration. 2.Anabolism involves synthetic reactions and includes protein synthesis. 3.Cell respiration produces sugar for energy storage. 4.Photosynthesis involves the use of captured sunlight energy and carbon dioxide.

Answer 1

Answer:

3.Cell respiration produces sugar for energy storage.

Explanation:

The process of cellular respiration does not produce sugars. This is a catabolic pathway that breakdown nutrients such as sugars. In the presence of oxygen, sugars are completely oxidized into CO2 and H2O. The energy stored in the chemical bonds of sugars is used to make ATP. The process occurs in three steps: glycolysis, citric acid cycle and electron transport chain. ATP is the energy currency of the cells. Therefore, cellular respiration produces ATP, not sugars.

Answer 2

Answer:

The correct answer is - option 3.

Explanation:

Catabolism is the process that is degradative, braking down the complex molecules in to simpler to produce energy, and include oxidation. Cellular respiration is the catabolic process that breaks down the sugars to produce energy for various cellular functions.

Cellular respiration does not produce sugar as it is the process that include the degradative action on sugar. Anabolic reaction such as protein synthesis as they produce protein or polypeptide chain.

Thus, the correct answer is - option 3.
