EVERYDAY SCIENCE

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: -Mitochondria are structures within cells that convert the energy from food into a form that cells can use. Each cell contains hundreds to thousands of mitochondria, which are located in the fluid that surrounds the nucleus (the cytoplasm).

Detailed explanation-5: -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.
