Intro to Metabolism

Question 1

1. The chief energy currency of all cells is a molecule calledNADHFADHATPEnzyme

Answer 1

ATP

Question 2

1. ATP is useful as an energy carrier becauseit can store large amounts of energy in one molecule so few are needed.it can release energy from one molecule in several stages as each phosphate group is removed.it is always at equilibrium with ADP in a cell.the bond linking the terminal phosphate to the rest of the molecule is energy rich but unstable.

Answer 2

it can release energy from one molecule in several stages as each phosphate group is removed.

Question 3

1. An example of catabolism would beassembling cellulose from glucose.photosynthesisanaerobic respirationtransport across membrane

Answer 3

anaerobic respiration

Question 4

1. NAD and FAD areenergy carriersenzymesthe chief energy currencyexamples of catabolism

Answer 4

energy carriers

Question 5

1. Oxidation and reduction reactions are chemical processes that result in a gain or loss in

Answer 5

electrons
