Answer 3

releases energy

usually to accomplish task

Question 4

what is an endergonic process?

Answer 4

absorbs energy

Question 5

What are the first and second laws of thermodynamics?

Answer 5

1. energy can not be created or destroyed, only transferred

2. energy transfers from high to low concentration

Question 6

what are the 3 forms of biological work?

Answer 6

1. chemical
2. mechanical
3. transport (among cells)

Question 7

what is a coupled reaction?

Answer 7

exergonic drives endergonic

Question 8

what are competitive enzyme inhibitors?

Answer 8

resemble the normal substrate and attaches at the enzymes active site

cannot change enzyme

inhibits enzyme’s interaction with it’s substrate

Question 9

What are noncompetitive inhibitors?

Answer 9

do not resemble enzyme’s substrate

does not bind to active site

change enzyme’s structure and ability to catalyze the reaction

Question 10

how do coenzymes assist enzyme action?

Answer 10

1. binding substrate to enzyme

2. transport biologic compounds from one enzyme to another

Question 11

what is condensation?

Answer 11

structural components of nutrients bind together to form more complex molecules and compounds
