Write the chemical equation for photosynthesis.
In which cell organelle does photosynthesis occur?
Explain the movement of carbon dioxide and oxygen in/out of a leaf during photosynthetic
process? (which goes in? which goes out?)
Name two factors that will determine the rate of photosynthesis?
In the diagram below, what gas do the bubbles contain? Hint: the gas is produced by
the plant.
Respiration

Which part of this energy flow shows respiration? (A, B, or C)

In which cell part does respiration take place?
Write the equation for respiration.
In the equation written above, what are the products? What are the reactants?
Describe how ATP releases energy as it is converted to ADP. Use the words “energy”
and “phosphate group” in your answer.
Read the paragraph below and answer the questions 6 and 7.
A student added 10 mL of a yeast suspension and 10 mL of water to two test
tubes. Yeast cells are heterotrophs. The student then added 5 grams of glucose
to one of the test tubes. Both test tubes were gently swirled to mix the contents
and then placed in a warm water bath for 15 minutes. During that time, the
student counted the gas bubbles that formed in each tube.

Draw and label a pH scale with “neutral”, “acid” and “base”.
Draw an enzyme-substrate complex. Label: active site, enzyme, substrate.
Explain how heat or a change in pH affects enzyme function. Use “active site”, “enzyme”
and “substrate” in your answer.
Which of the 4 organic compounds would an enzyme be?
According to the graph below, what is the optimum pH for pepsin to function? How about
trypsin?
Circle the graph below shows how an enzyme’s function is affected by temperature?
Hint:
enzymes won’t function well at temperatures that are too low or too high!
