5.2 Study Guide

Question 1

Define Metabolism

Answer 1

the whole sum of reactions that occur throughout the body within each cell and that provide the body with energy

Question 2

Define Anabolic

Answer 2

the bio-synthetic buildup of cell material from simple inorganic or organic compounds

Question 3

Define Catabolic

Answer 3

supplies all the energy

Question 4

Define Exergonic

Answer 4

a reaction that releases free energy

Question 5

Define Endergonic

Answer 5

a reaction that requires energy to be absorbed in order for it to take place

Question 6

Define Hydrolysis

Answer 6

a chemical reaction in which water is used to break down a compound

Question 7

Define synthesis

Answer 7

the process of combining two or more components to produce an entity

Question 8

The ATP cycle

Answer 8

the source of energy for use and storage at the cellular level

Question 9

Which parts of the ATP cycle correlate with the vocab terms above.

Answer 9

~ Anabolic = synthesis
~ Catabolic = hydrolysis
~ Exergonic = hydrolysis = catabolsim
~ Endergonic = synthesis = anabolism

Question 10

Give an example of an exergonic reaction being linked with an endergonic reaction and why they must occur in that order.

Answer 10

A glow stick is an excellent example of a reaction that is exergonic, yet not exothermic. The chemical reaction releases energy in the form of light, yet it doesn’t produce heat. These reactions must occur in this order because exergonic reactions occur on their own as there is no need of the energy to initiate these reactions whereas endergonic reactions requires some amount of the energy to initiate it. The required energy from the exergonic reactions provide a large amount of energy in by breaking the bonds.
