RESPIRATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Where in the cell does cell respiration occur?
A
Chloroplast
B
Mitochondria
C
Vacuole
D
Cytoplasm
Explanation: 

Detailed explanation-1: -While most aerobic respiration (with oxygen) takes place in the cell’s mitochondria, and anaerobic respiration (without oxygen) takes place within the cell’s cytoplasm.

Detailed explanation-2: -In the mitochondria, cellular respiration occurs in the mitochondrial matrix through the Krebs cycle to form ATP, FADH2 and NADH. The formed FADH2 and NADH then go into the inner mitochondrial membrane where they are involved in the electron transport chain to form more ATP molecules.

Detailed explanation-3: -Mitochondria have an important role in cellular respiration through the production of ATP, using chemical energy found in glucose and other nutrients. Mitochondria are also responsible for generating clusters of iron and sulfur, which are important cofactors of many enzymes.

Detailed explanation-4: -Cellular respiration takes place in the cells of all organisms. In the cell, the food (glucose) is broken down into carbon dioxide and water using oxygen. When breakdown of glucose occurs with the use of oxygen it is called aerobic respiration.

Detailed explanation-5: -Cellular respiration is a process that occurs in the mitochondria of all organisms. In this process, both plants and animals break down simple sugars into carbon dioxide and water and release energy in the form of adenosine triphosphate (ATP).
