Chapter 5 Flashcards
Exergonic reaction is a ____________ reaction.
Catabolic
Endergonic reaction is a ___________ reaction.
Anabolic
What do exergonic reactions do?
Release potential energy.
What do endergonic reactions do?
Store, conserve or increase free energy.
Is cell respiration endergonic or exergonic?
Exergonic
Explain how cell respiration is exergonic.
In the presence of oxygen, cells extract the chemical energy stored in the CHO, lipid and protein molecules fir energy. Energy is either conserved in chemical compounds for use or flows to the environment for heat.
Oxidation is gain or loss of electrons?
Loss
Reduction is gain or loss of electrons?
Gain
net gain or loss in valence electrons for oxidation?
Net gain in valence electrons.
net gain or loss in valence electrons for reduction?
Net decrease in valence electrons.
