What are the names of the 2 types of reactions that occur in the chloroplasts? Write the name of each type of reactions in the correct space on the picture (where the words have been erased with white out).

Answer explanation

The two reactions that occur within photosynthesis are Light Dependent and Light Independent/Calvin's Cycle.

Select the correct description of the processes happening in A and B on the image.

• A) A phosphate group is attached to ADP from eating/processing food, so that energy can be absorbed;

  B) One of the phosphate bonds located on ATP is broken, so that energy can be released for the cell to use.

• A) A phosphate group is attached to ADP from eating/processing food, so that energy can be released;

  B) One of the phosphate bonds located on ATP is broken, so that energy can be absorbed for the cell to use.

• A) A glucose group is attached to ADP from eating/processing food, so that energy can be absorbed;

  B) One of the glucose bonds located on ATP is broken, so that energy can be released for the cell to use.

• There is not enough information to determine what is happening in between ATP and ADP.

Answer explanation

ATP loses a phosphate group by the breaking of a chemical bond, which turns it into ADP.

ADP must gain another phosphate group to turn back into ATP.

A group of students are attempting to measure the rate of photosynthesis for an underwater plant. Their teacher instructed them to count the amount of bubbles coming from the plant. Which student is correct in identifying what was being produced and why?

• Student A:  The bubbles represent oxygen because oxygen is produced during photosynthesis.

• Student B:  The bubbles represent hydrogen because hydrogen is produced during photosynthesis.

• Student C:  The bubbles represent water because water is produced during photosynthesis.

• Student D:  The bubbles represent carbon dioxide because carbon dioxide is produced during photosynthesis.
