Proteins, Carbs, & Lipids - Macromolecules Characterize Living Things & Proteins Are Polymers with Highly Variable Structures

Question 1

Monomers

Answer 1

small molecules that form polymers

Question 2

Isomers

Answer 2

molecules with the same chemical formula with different atom arrangement
Ex: cis-trans isomers, optical isomers

Question 3

What type of reactions produce water? What type of reactions consume water?

Answer 3

condensation (build); hydrolysis (break apart)

Question 4

What is the primary structure of a protein? Secondary? Tertiary? Quaternary?

Answer 4

sequence of amino acids; a-helix & B pleated sheet; folds protein into a 3D shape; two or more polypeptide chains form

Question 5

What happens if a protein is heated? Is cooled?

Answer 5

secondary & tertiary structure break down, protein becomes denatured; returns to normal tertiary structure
