Biochemistry

The study of the transformation of energy in

living organisms.

• biomolecules

• bioenergetics

• macromolecules

• cyanocobolamine

--------------are examples of bioenergetic processes.

• Glycogenesis

• gluconeogenesis,

• citric acid

• all

Bioenergetics is the branch of biochemistry

that focuses on how cells transform energy,

often by producing, storing or consuming

-------------

• ADP

• ATP

• NADPH

• APP

The energy that cells can and must use is free

energy, described by the

• E

• F

• G

• H

the free energy is ---------, we

are looking at changes in enthalpy and entropy

that favour the process and it occurs

• POSITIVE

• NEGETIVE

• NEUTRAL

• HIGH

In exergonic reaction the free energy of the

products is ----------- than that of the reactants;

• HIGHER

• LOWER

• MORE

• EQUAL

If the temperature of the surroundings -----------, the reaction is endothermic

• INCREASES

• DECREASES

• HIGH

• LOWER

an endergonic reaction involves ---------- of energy.

• release

• absorption

• increase

• decrease

Exergonic reactions release free energy; the ∆G for that reaction will be a ----------- value.

• positive

• negative

• neutral

• high

endergonic reactions involve a ------ in energy, that energy has to be supplied from an outside source in order for the reaction to occur

• gain

• loss

• high

• low
