Enzymes

Metabolism

Sum of all chemical reactions in an organism

Catabolism

Breakdown of complex molecules

Releases energy

Anabolism

Synthesis of complex molecules (monomers to polymers)

Uses energy

Exergonic

Catabolic reactions fall under this category

Endergonic

Anabolic reactions fall under this category

Catabolic

What kind of reaction is characterized as being “spontaneous”? (catabolic or anabolic)

Enzymes

Proteins and biological catalysts regulating cell metabolism are known as?

Substrate

Enzymes act on a molecule called?

Active site

Enzyme activity depends on the enzyme’s shape and its ______ ____. (which is the binding area for the substrate)

ase

what is the common suffix usually used for naming enzymes?

Catalysts

What provides an alternative pathway of lower activation energy?

yes

Do enzymes lower the activation energy of a reaction?

substrates

When _________ are forced to collide at the right angles, they will bond and change into the product(s).

Catabolic

What kind of reaction would put stress on existing bonds in substrates

substrates

in a chemical reaction, the ___________ are reactants.

Digestive

What kind of enzyme works by stressing the bonds between the single units (monomers) of our food (polymers).

Monosaccharides

Carbohydrates would be digested into

hydrolysis

what is the most common reaction that breaks most macronutrients apart?

Fatty acids

Lipids would be digested into?

s

Quick note (press s to skip)

Enzymes and substrates collide based on molecular motion. This is why temperatures speed up reactions - there are more collisions!

yes

Can enzymes change shape and either stress the bonds or make it easier for bonds to form in substrates?

s

Quick note (press s to skip)

Temperature, pH and salinity changes can result in a protein shape change

homeostasis

the process of maintaining an optimum set of conditions is also known as?

Denaturation

If the active site changes shape, it makes it hard for the enzyme to catalyze the reaction. This is also called?

Yes

Does Van’t Hoffs Rule state that every increase in 10 degrees results in the rate of a chemical reaction doubling?

40

about what temperature do H-bonds start breaking
