2303111 Summary Of Bioenergetic Concept

Front 1

a form of potential energy that is stored in molecules and may be released during chemical reactions

Back 1

chemical

Front 2

name of the system that neither energy nor matter can enter or leave

Back 2

isolated

Front 3

name of the inhibition process by which two or more molecules that are somewhat similar in structure compete for the active site of an enzyme is called.......

Back 3

competitive

Front 4

name of a pair of reactions, one exergonic and one endergonic, that are linked together such that the energy produced by the exergonic
reaction provides the energy needed to drive the endergonic reaction.

Back 4

coupled

Front 5

name of energy needed to start reaction

Back 5

activation

Front 6

name of the region of an enzyme molecule that binds substrates and performs the catalytic function of the enzyme.

Back 6

active site

Front 7

name of regulation process by which enzyme action is enhanced or inhibited by small organic molecules by binding to the enzyme at a regulatory site distinct from the active site

Back 7

allosteric

Front 8

name of a substance that speeds up a chemical reaction without itself being permanently changed in the process

Back 8

catalyst

Front 9

ืname of a chemical reaction that
requires an input of energy to proceed

Back 9

endergonic

Hint 9

uphill

Front 10

a measure of the amount of randomness and
disorder in a system

Back 10

entropy

Front 11

name of a biological catalyst, usually a protein, that speeds up the rate of specific biological reactions.

Back 11

enzyme

Front 12

name of a chemical reaction that releases
energy (either as heat or in the form of increased entropy)

Back 12

exergonic

Hint 12

downhill

Front 13

name of the
condition in which the product of a reaction inhibits one or more of the
enzymes involved in synthesizing the product.

Back 13

feedback inhibition

Front 14

the energy of movement; includes light, heat, mechanical movement, and electricity

Back 14

kinetics

Front 15

a sequence of chemical reactions within a cell in which the products of one reaction are the reactants for the next reaction.

Back 15

metabolic pathway

Front 16

of all chemical reactions that occur within a
single cell or within all the cells of a multicellular organism

Back 16

metabolism

Front 17

kind of energy that is "stored"

Back 17

potential

Hint 17

including chemical energy (stored in
molecules), elastic energy (such as stored in a spring), or gravitational
energy (stored in the elevated position of an object)

Front 18

the atoms or molecules that are the reactants for an enzyme catalyzed chemical reaction

Back 18

substrate

Front 19

name of a process that energy transferred to an object, usually causing the object to
move

Back 19

work
