Question 1

what is an exergonic reaction

Answer 1

an energy releasing chemical reaction that produces products that contain less potential energy than their reactants

Question 2

what is an endergonic reaction

Answer 2

an energy requiring chemical reaction that produces products with lots of potential energy

Question 3

what is a spontaneous reaction

Answer 3

a chemical reaction that will proceed on its own, without any outside influence

Question 4

what is the role of enzymes in chemical reactions

Answer 4

lowering the activation energy of specific biochemical reactions

Question 5

what influences an Enzyme? (3)

Answer 5

inhibitors, pH, temperature

Question 6

what are bioenergy carriers

Answer 6

ATP

Question 7

what is the structure of ATP (3)

Answer 7

3 phosphates
adenine
Ribose

Question 8

what is substrate level phosphorylation

Answer 8

ATP is formed when a phosphate group is transferred to ADP

Question 9

What is chemiosmosis regarding producing ATP

Answer 9

process of which phosphorylation of ADP to form ATP is coupled by the transfer of electrons down an electron transport chain
