STORED IN NUTRIENTS
Describe the process of glycolysis. Discuss evolutionary perspective of glycolysis. Write note on fermentation. Discuss different steps of Krebs cycle. Draw Krebs cycle. Describe different steps of electron transport chain. Give number of molecules of ATP produced during respiration of one molecules of glucose.
TERMS DEFINITIONS Electron transport chain • The collection of molecules embedded in the inner membrane of the mitochondrion is called electron transport chain Krebs cycle Krebs cycle is a series of reactions in which the pyruvate from glycolysis is oxidized to CO2. Thermodynamics
RESPIRATION Animals require a constant supply of energy. This energy performs biological work. The ATP provides this energy. All animals can generate ATP by breaking down organic nutrients. These nutrients are carbohydrates, fats, and proteins. Energy is released during respiration. This energy is used
