• amino acid

Amylase is an enzyme that breaks down starch. Why doesn't it work when it hits the stomach?

• enzymes have been used up

• enzymes get too hot

• enzymes only function where they start working

• enzymes require a specific pH

What increases when chromatin is replicated?

• amount of DNA

• amount of ATP

• number of vacuoles

• number of ribosomes

What are the products of the light dependent reactions of photosynthesis?

• glucose

• CO2

• ATP, NADPH, H+, O2

• H20

Acid rain causes pH changes in lakes and rivers that would affect what?

• inhibits enzyme activity

• breaks down nutrients in water

• blocks sunlight from reaching fish

• increase O2 levels in the water

What occurs during the S phase of interphase?

• DNA is replicated

• cytoplasm must be separated

• chromosomes must be joined

• cell membrane must be expanded

What are the subunits of proteins?

• lipids

• sugars

• starches

• amino acids

Changes in DNA during cell reproduction can cause cancer. What does this affect?

• mitosis

• waste disposal

• photosynthesis

• respiration
