Respiratory Balance Sheet & Amphibolic Pathway: Cellular Respiration: XI Biology

This video explores the intricate processes of respiration i.e.,complete oxidation of glucose molecules to produce ATP.The respiratory balance sheet refers to every living cell which constantly gains or loses energy. A balance sheet can be formed for the gain and loss of energy using ATP in a cell.
The respiratory pathway is an amphibolic pathway because it involves both catabolic and anabolic processes.
Catabolic processes
The respiratory pathway breaks down complex molecules like glucose, fats, and proteins into simpler molecules to release energy. e.g., glucose is broken down into pyruvate in the cytoplasm.
Anabolic processes
The respiratory pathway uses intermediates from the breakdown of biomolecules to synthesize other biomolecules, like proteins and fatty acids.
e.g., the respiratory pathway uses acetyl-CoA to synthesize fatty acids.
