Enzyme Review

what temperature does this enzyme work best at

40oC

Denature

A change in the shape of a protein (such as an enzyme) can be caused by changes in temperature or pH (among other things).

Anabolic

A process in which large molecules are built from small molecules

Amylase

An enzyme in saliva that breaks the chemical bonds in starches

digestion

Breakdown of food substances into simpler forms that can be absorbed and used

activation energy

Energy needed to get a reaction started

As the temperature increases above the optimum temperature

Enzyme activity decreases

maltase enzyme

Maltase acts on maltose in the small intestine, converting it into glucose.

Base (Alkaline)

PHs are greater than 7 are basic (Alkaline

What is acid?

PHs less than 7 are acidic

The function of a specific enzyme is most directly influenced by its

Physical shape

Enzymes

Proteins that speed up chemical reactions

What is the role of citric acid when add to apple slices?

Slows the rate of enzyme action and prevents browning

catalyst

Substance that speeds up the rate of a chemical reaction

active site

The part of an enzyme or antibody where the chemical reaction occurs.

An enzyme's shape is determined by

The sequence of amino acids in its structure

amino acids

building blocks of proteins

Synthesis

combining parts into a whole (Make)

What is a pH level?

pH is a measure of how acidic/basic water is

Substrate

reactant of an enzyme-catalyzed reaction
