At the end of the calvin cycle, this molecule is regenergated: Select one: a. a five carbon molecule, ribulose bis-phosphate b. a six carbon molecule, glucose c. a polymer, cellulose d. a three carbon molecule, glyceraldehyde-3-phosphate e. a four carbon molecule, malate

You are a marine biologist sampling an offshore ecosystem. One day, you find a red organism floating in one of your nets. It has structures that resemble the leaves and stems of a plant. You hypothesize that this organism might be photosynthetic. Describe how you could test this hypothesis using a pH indicator solution. a. In detail, describe the steps you would take and the reactants of photosynthesis required. b. What change in pH would indicate that the organism was undergoing photosynthesis, and how would the indicator respond?

Researchers can use solvents to extract, or break apart, components of a cell or tissue to separate and/or isolate components. If you extracted some cells with a non-polar organic solvent, what would the solvent contain the MOST of at the end of the process? A. chlorophyll B. ATP C. Glucose D. hydrogen ions

Which of the following would be a location where complexes of the electron transport chain could be found in plant cells? Select one: a. matrix of mitochondria b. thylakoid membranes of chloroplasts c. outer membrane of mitochondria d. cytoplasm e. stroma of chloroplasts

The denaturation temperature of rubisco in a certain plant was determined to be 76.2 degrees Celsius. What happens to the rate of photosynthesis if the temperature continues to increase?   A. The rate of photosynthesis will increase.   B. The rate of photosynthesis will decrease.   C. The rate of photosynthesis will remain the same.   D. The rate of photosynthesis will decrease, then increase.

What are the roles of ATP and NADPH in photosynthesis?     a. ATP and NADPH are forms of chemical energy produced from the light dependent reactions to be used in the light independent reactions that produce sugars. b. ATP and NADPH are forms of chemical energy produced from the light independent reactions, to be used in the light dependent reactions that produce sugars. c. ATP and NADPH are forms of chemical energy produced from the light dependent reactions to be used in the light independent reactions that produce proteins. d. ATP and NADPH are forms of chemical energy produced from the light dependent reactions to be used in the light independent reactions that use sugars as reactants.
