Enzymes

Question 1

Enzymes

Answer 1

Biological catalysts that speed up the rate of chemical reactions in living cells by reducing the required activation energy

Question 2

Competitive Inhibitor vs Non-competitive

Answer 2

Competitive is similar shape to substrate and binds to active site of enzyme, preventing substrate from binding
Non-competitive binds to allosteric site, altering the shape of the enzyme so the substrate will no longer fit in place with the active site

Question 3

Factors that affect enzymes activity

Answer 3

Temperature (curve will fall)
pH (curve will fall)
Substrate Concentration (plateau as reaches saturation point)
Enzyme Concentration (plateau - increases amount of product made per unit of time)
