Chapter 6- Enzymes

Question 0

Metabolic Pathway

Answer 0

A specific molecule is altered in a series of defined steps, resulting in a product

Question 1

Metabolism

Answer 1

Totality of a organism’s chemical reaction, also a emergent property

Question 2

Catabolic Pathway

Answer 2

A metabolic pathway that releases energy, by breaking down complex molecules into simpler ones

Question 3

Anabolic pathway

Answer 3

A metabolic pathway that consumes energy to create complex molecules from simpler ones

Question 4

Bioenergetics

Answer 4

The study of how energy flow through an organism

Question 5

Energy

Answer 5

The capacity to cause change or do work

Question 6

Kinetic energy

Answer 6

The energy associated with the relative motion of objects

Question 7

Thermal energy

Answer 7

Random movement of atoms or molecules in an object

Question 8

Heat

Answer 8

The transfer of thermal energy from one substance to another

Question 9

Potential energy

Answer 9

The energy something possess because of it location or structure

Question 10

Chemical energy

Answer 10

Energy available for release in a chemical reaction

Question 11

Thermodynamics

Answer 11

Study of energy transformations that occur in a collection of matter

Question 12

1st Law of Thermodynamics

Answer 12

The energy of the Universe is constant: Energy can be transferred and transformed but it can not be created or destroyed

Question 13

Entropy

Answer 13

The measure of disorder or randomness

Question 14

Second law of Thermodynamics

Answer 14

Every energy transfer increases the entropy of the universe

Question 15

Spontaneous Process

Answer 15

A process that can occur without an input of energy

Question 16

Free Energy

Answer 16

The portion of a systems energy that can perform work when the temperature and pressure are uniform throughout the system, like a living cell

Question 17

Exergonic reaction

Answer 17

Process with a net release of energy

Question 18

Endergonic Reaction

Answer 18

A reaction that absorbs energy from its surrounding

Question 19

Phoshorylated Intermediate

Answer 19

A reactant with phosphate attached to it

Question 20

Activation energy

Answer 20

The energy needed to start a reaction, or to push a reactants uphill to start

Question 21

Enzyme

Answer 21

A protein that speeds up the reaction of something like a catalyst

Question 22

Catalyst

Answer 22

A chemical agent that speeds up a reaction without being consumed by a reaction

Question 23

Substrate

Answer 23

The reactant of an enzyme

Question 24

Enzyme-substrate Complex

Answer 24

The period when an enzyme and the substrate are attached to each other

Question 25

Induced Fit

Answer 25

When an enzyme changes the shape of it active site causing a snugger fit

Question 26

Cofactors

Answer 26

Nonprotein helpers attached to the enzyme that help speed up the catalytic process, either attach tightly and permeant or loosely and replaceable

Question 27

Coenzyme

Answer 27

An Organic molecule that attaches to the enzyme and speeds up catalytic process

Question 28

Competitive Inhibitors

Answer 28

A molecule that attempts to attach to the active site of an enzyme and block substrates from getting in

Question 29

Noncompetitive Inhibitors

Answer 29

A inhibitor attached to a point on the enzyme that is not the active site but still inhibits the rate of catalysis

Question 30

feedback inhibition

Answer 30

When the product of a metabolic pathway inhibits the process by attaching to the enzyme

Question 31

Energy coupling

Answer 31

Use of a exergonic process to start a endergonic

Question 32

ATP

Answer 32

Adenosine Triphosphate
