Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Where is the cell does respiration occur?
A
Cytoplasm
B
Cell membrane
C
Mitochondria
D
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: -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: -Ribosomes are essential for protein synthesis, but they are present in mitochondria and plastids, the sites of respiration and photosynthesis.

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: -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.
