3.6 Enzymes

Question 0

Define active site.

Answer 0

Area and enzyme designed to match specific substrate

Question 1

Define enzyme

Answer 1

proteins long chains of amino acid is that have a 3-D shape that are very specific and catalyze chemical reactions.

Question 2

Explain enzyme substrate specificity through lock and key model

Answer 2

Actisite is exactly the same shape of the substrate, substrate seems to be attracted to enzyme, fit together like a lock and key, explains why enzymes are specific only work for one reaction.

Question 3

Explain and enzyme-substrate specificity through induced fit model

Answer 3

Actisite still look identical to substrates, enzymes goes a slight change in shape to bond with substrates, but a reaction complete products released, enzyme returns to regular shape.

Question 4

Explain the effect of temperature on enzyme activity

Answer 4

Increased temperature increase molecular motion resulting in more collisions and more kinetic energy.

Decreased temperature slows down molecular motion slows down reaction.
Each enzyme has optimum temperature is too high Willedee nature.

Question 5

Explain your facts of pH concentration on enzyme activity

Answer 5

Active sites an enzyme have amino acid is which are charge positive or negative sub trades must be opposite charge for a reaction.

If solutions too acidic will bond to negative active sites or substrate, changing its charge substrates = less effective ineffective reaction
(Same to be done if too basic.)

Or near as positive negative charges can cause enzyme to denature

Question 6

Explain the effects of substrate concentration on enzyme activity.

Answer 6

If substrate concentration increases rate of reaction increases if you have more reactant molecules there are more to collide however there is a limit enzymes have a max rate which they can work.

Question 7

Define Denaturation

Answer 7

Is a structural change and a protein that results in a loss usually permanent of its biological properties occurs when temperatures to higher pH levels are off.

Question 8

Explain the use of lactase in the production of lactose-free milk.

Answer 8

ANZUS name is lactase helps digest this sectile read lactose two monosaccharides to be absorbed into the bloodstream. Milk products can be treated by purifying lactase from East or bacteria and binding it into an art substance such as allerbeBB equals lactose-free
