a.
To list:
Two electron carriers used in biological cells and summarize the role they play in the production of ATP.
Concept introduction:
Electron carriers are chemical molecules which release and add electrons during the process of electron transport chain. In this process, one molecule which gives electrons is oxidized and substance which accepts electrons is reduced.
b.
To explain:
Based upon the information in Table 8.2 “A sampling of enzymes, their substrates and their products”, (given in the textbook), explain which type or types of enzyme supply electrons to these carriers.
Concept Introduction:
Enzymes are classified as “hydrolases, oxidoreductases, lyases, ligases, isomerases, and transferases” according to the mechanism inside the cell. In each mechanism, a substrate molecule is involved which gets converted to form a product with the use of coenzymes like NADH and FADH2.
