METABOLISM OF FATS AND PROTEINS
abidaALTERNATIVE FOOD MOLECULES The catabolism of glucose is the most common metabolic pathway in cells. But animals also consume fats and proteins. These may be used to harvest energy. Fats…
THE ENERGY SCORE FOR AEROBIC RESPIRATION
A BALANCE SHEET T eukaryotic cell obtains a net gain of 36 ATP molecules from the breakdown of ach glucose molecule. 1. GI colysis: Glycolysis produces four ATP molecules. But…
AEROBIC RESPIRATION: THE MAJOR SOURCE OF ATP
The glycolysis and fermentation are inefficient processes. Thus the end product of glycolysis (pyruvate) still contains large amount of energy. This energy can be released by further oxidation. Free oxygen…
GLYCOLySIS
Glycolysis is the initial step of catabolic chemical reactions. It occurs almost in all the cells. Six-carbon glucose molecule is broken down into two molecules pyruvate during glycolysis. Pyruvate is…
HOW CELLS HARVEST ENERGY STORED IN NUTRIENTS
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…

DEFINITIONS AND KEY POINTS OF ENERGY AND ENZYME
TERMS DEFINITIONS Energy The capacity, to do work is called energy. Work Work is the transfer of energy. Thermodynamics The study of energy is called thermodynamics…
NOW CELLS CONVERT ENERGY: AN OVERVIEW
Animals make ATP in two ways: Substrate level phosphorylation The synthesis of ATP during reaction of glycolysis and Krebs cycle is called substrate level phosphorylation. ATP formation from ADP and…
