Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What do we call the process by which glucose is broken down and energy is released?
A
breathing
B
photosynthesis
C
respiration
D
perspiration
Explanation: 

Detailed explanation-1: -Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.

Detailed explanation-2: -Glycolysis is a series of reactions that extract energy from glucose by splitting it into two three-carbon molecules called pyruvates.

Detailed explanation-3: -Once glucose is digested and transported to your cells, a process called cellular respiration releases the stored energy and converts it to energy that your cells can use. Cellular respiration consists of three metabolic processes: glycolysis, the Krebs cycle, and oxidative phosphorylation.

Detailed explanation-4: -During glycolysis, glucose ultimately breaks down into pyruvate and energy; a total of 2 ATP is derived in the process (Glucose + 2 NAD+ + 2 ADP + 2 Pi–> 2 Pyruvate + 2 NADH + 2 H+ + 2 ATP + 2 H2O). The hydroxyl groups allow for phosphorylation. The specific form of glucose used in glycolysis is glucose 6-phosphate.

Detailed explanation-5: -The process of breakdown of food in the cell with the release of energy is called cellular respiration.
