5.2 study guide

Question 1

Metabolism

Answer 1

all the chemical processes going on continuously inside your body that allow life and normal functioning

Question 2

Anabolic

Answer 2

the set of metabolic pathways that construct macromolecules like DNA or RNA from smaller units

Question 3

Catabolic

Answer 3

marked by or promoting metabolic activity concerned with the breakdown of complex molecules (such as proteins or lipids) and the release of energy within the organism

Question 4

Exergonic

Answer 4

A process such as a chemical reaction in which the Gibbs free energy (G) of the products is smaller than the Gibbs free energy of the reactants

Question 5

hydrolysis

Answer 5

a common form of a chemical reaction where water is mostly used to break down the chemical bonds that exists between a particular substance

Question 6

synthesis

Answer 6

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

Question 7

The ATP cycle

Answer 7

ADP is converted to ATP by the enzyme ATP synthase by adding inorganic phosphate to ADP. ATP is then broken down to ADP and inorganic phosphate by the same enzyme when the body uses the energy stored in its bonds. ADP is then recycled to produce ATP again.

Question 8

What a graph of an exergonic and endergonic reaction look like in terms of energy of reactants and products

Answer 8

Exergonic- it went lower because more energy is being released.

Endergonic- it went higher because its inputting energy it requires.

Question 9

Relate vocab terms to each other. I.e. is an anabolic reaction exergonic or endergonic?

Answer 9

anabolic = endergonic

catabolic = exergonic
