Enzymes :O

Question 1

What are the functions of enzymes?

Answer 1

Speed up rxn’s in the body by lowering activation energy, catabolic and anabolic,

Question 2

Define anabolic rxn

Answer 2

Molecules drawn to an active site, bonds formed between molecules, endergonic, to one molecule. e.g. Protein synthesis

Question 3

Define catabolic rxn

Answer 3

Molecule drawn into an active site and bonds split apart, release energy (exergonic). e.g. digestion

Question 4

Name ways the rxn rate be increase

Answer 4

Increase temp., increase concentration, enzymes

Question 5

What affects enzyme function

Answer 5

ph, temperature (denaturation), substrate or enzyme conc., inhibitors

Question 6

What are co-factors?

Answer 6

Vitamins, Metals, or certain co-enzymes which enzymes need to help the reaction. Can activate and deactivate an enzyme.

Question 7

What is an enzyme structure/makeup?

Answer 7

Proteins, globular shape, complex 3D structure (tertiary)

Question 8

What permits a chemical
rxn to proceed
easily?

Answer 8

The shape and the chemical environment of the active site

Question 9

Define Endergonic

Answer 9

The use ‘work’ energy common in forming bonds

Question 10

Define Exergonic

Answer 10

The release of ‘work’ energy common in breaking bonds
