Question 2

What process are peptide bonds formed though

Answer 2

Dehydration synthesis or translation

Question 3

What process breaks peptide bonds

Answer 3

Hydrolysis

Question 4

What are peptide bonds

Answer 4

Covalent bonds that hold amino acids together

Question 5

What are active sites

Answer 5

The part of an enzyme that temporarily combines with portions of the substrate

Question 6

What does amylase break down and where is it produced?

Answer 6

Breaks down starch and glycogen. Produced in the salivary glands

Question 7

What does pepsin break down and where is it produced?

Answer 7

Breaks down protein digestion. Produced by the gastric glands

Question 8

What does sucrase, lactase, and maltase break down and where is it produced

Question 9

What are essential amino acids

Answer 9

Amino acids that the body cannot synthesize

Question 10

What are complete vs. incomplete proteins

Answer 10

Complete proteins contain all of the essential amino acids

Question 11

How can enzymes speed up chemical reactions

Answer 11

An enzyme might bind to a substrate in a way that changes the shape of it, making it easier for the substrate to react
