Enzymes required for respiratory chain are present on/in:
Correct answer: A. Cristae
- A. Cristae
- B. Mitochondrial matrix
- C. Inter-membrane space
- D. Cytoplasm
Explanation
Cristae (singular: crista) are internal, folded structures found in the inner mitochondrial membrane. Mitochondria are membrane-bound organelles known as the "powerhouses of the cell" due to their role in energy production through oxidative phosphorylation. Cristae provide an increased surface area for various mitochondrial activities, especially those related to the electron transport chain and ATP synthesis.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
