AEROBIC RESPIRATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Where does respiration takes place?
A
muscles
B
mitochondria
C
nucleus
D
ribosomes
E
chloroplasts
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: -Ribosomes are essential for protein synthesis, but they are present in mitochondria and plastids, the sites of respiration and photosynthesis.

Detailed explanation-3: -The initial process of respiration occurs in the cytoplasm of the cell and completes in the mitochondria of a cell. There are mainly two phases of respiration-glycolysis and Kreb’s cycle. Glycolysis occurs in the cytoplasm of a cell and Kreb’s cycle occurs in the mitochondria of a cell.

Detailed explanation-4: -Mitochondrial respiration is the set of metabolic reactions and processes requiring oxygen that takes place in mitochondria to convert the energy stored in macronutrients to adenosine triphosphate (ATP), the universal energy donor in the cell.

Detailed explanation-5: -Mitochondria, using oxygen available within the cell convert chemical energy from food in the cell to energy in a form usable to the host cell. The process is called oxidative phosphorylation and it happens inside mitochondria.
