Plants that carry out crassulacean acid metabolism (CAM) differ from C4 plants in that they do not contain rubisco. their stomata are open at night. they do not need ATP for photosynthesis. they do not carry out the Calvin cycle. they do not contain PEP carboxylase. O O O O

Photorespiration causes a number of impacts on a plant.  Which of these drives the ECOLOGICAL difference between C3 and C4 plants   Question 4 options:   Rubisco mistakes Oxygen for CO2   The plant uses energy to convert the toxic product of photorespiration back into something less harmful   The plant needs a large number of enzymes to be able to regain the energy invested in the 2 carbon molecule produced by photorespiration   None of these explain the difference   The plant needs to do gas exchange to remove oxygen and add CO2 to the cell doing photosynthesis to avoid photorespiration.

Water is split during the Calvin Cycle of photosynthesis O True O False

Which of the following statements is TRUE?

1. During the light dependent reaction, the molecules within the membrane absorb light energy 2. high energy compounds light dependent portion of photosynthesis 3. an electron which is released by a process called and are produced in the in the thylakoid enters where it is energized and used to convert energy. 4. protons travel through located in the thylakoid membrane in a high energy compound. a process known as 5. The three stages of the light independent reaction are to produce and 6. The most abundant protein on earth is 7. You would need molecules of RuBp in order to create 1 molecule of glucose

Which of the following accepts an electron from water in photosynthesis? P680 in Photosystem II O P700 in Photosystem I Oxygen in Photosystem II O NADP* in Photosystem I

In CAM plants, the Calvin Cycle occurs during the day. O True O False
