ATP

Front

immediate energy currency of cells

Back

combustion and respiration

Front

2 examples of an exergonic reactions

Back

dynamic equilibrium

Front

Rate of change is exactly the same in both directions, like D in the diagram

Back

coupled reaction

Front

Input of free energy required to drive an endergonic reaction is supplied by an exergonic reaction, like respiration and photosynthesis

Back

work

Front

organisms use energy from their surrounding to do?

Back

endergonic

Front

reaction were free energy increases, stored in chemical bonds

Back

ADP

Front

ATP is formed by the phosphorylation of this molecule an endergonic process

Back

redox

Front

reaction in which an electron is transferred from one atom to another

Back

enzymes

Front

biological catalyst that increases speed of a chemical reaction without being consumed and Often end in "ase"

Back

activation energy

Front

initial imput of energy to start a chemical reaction

Back

first

Front

law of thermodynamics that states: Organisms capture energy from their surroundings to survive

Back

electrons

Front

NAD+ and NADP+ carry?

Back

exergonic

Front

reaction were free energy decreases as it is released

Back

1. PH 2. Temperature

Front

2 things that have a big effect on the rate of enzyme action, other than enzyme concentration

Back

substrate

Front

molecule that binds to an enzyme

Back

activation energy

Front

enzymes speed up chemical reactions by lowering?

Back

active site

Front

where a substrate binds to an enzyme

Back

oxidation

Front

when a substance gives up one or more electrons to another substance

Back

inhibition

Front

the regulation of enzymes by either competing with substrate for active site, or binding at a different (allosteric) site

Back

photosynthesis

Front

1 example of an endergonic reaction

Back

reduction

Front

when a substance receives one or more electrons from another substance

Back

decreases

Front

as entropy increases, the amount of free energy?

Back

free energy

Front

amount of energy available to do work

Back

change in free energy

Front

what does this chemical equation show ΔG = ΔH - TΔS

Back

catabolism

Front

degradation of large complex molecules into smaller simpler molecules, an exergonic reaction, like respiration or combustion

Back

energy

Front

the transfer of electrons is the transfer of?

Back

enthalpy

Front

total potential energy in a system

Back

sun

Front

ultimate source of energy for almost all organisms

Back

anabolism

Front

synthesis of complex molecules from simpler molecules, an Endergonic reaction, like photosynthesis or protein synthesis
