What is repiration and how do it work?

Answer 1

Respiration, also called cellular respiration, is the process when animal/plant cells break down glucose to release its energy. Respiration occurs in two stages: (1) Glycolysis, (2) Krebs Cycle/ citric acid cycle. Stage 1, glycolysis, occurs in the cytoplasm, when glucose is broken down a little, and 2 ATP (energy storages) are made. Stage 2, the Krebs Cycle/ citric acid cycle, occurs in the mitochondria of a cell, when the glucose molecules are really broken down; a large amount of energy is released, in the form of 34 ATP! Added together, the net total of ATP is 34. The cell will later use this energy to help the organism function.

Answer 2

Respiration is the process in which cells obtain energy by breaking down glucose and oxygen to produce carbon dioxide, water, and ATP. It occurs in multiple stages: glycolysis, the Krebs cycle, and oxidative phosphorylation. These processes take place in the cytoplasm and mitochondria of cells, allowing the conversion of nutrients into usable energy.
