Which molecule directly provides the energy for the reduction of carbon during the Calvin cycle?

ATP

Which of the following statements about CAM plants is false?

All CAM plants are flowering plants.

Give one example each of a C3 plant, a C4 plant, and a CAM plant.

An example of a C3 plant is rice, C4 is corn, and CAM is Spanish moss

Photosynthetically active pigments

absorb red and blue light

Metabolism refers to

all the chemical reactions that take place in cells and an organism as a whole

Photosynthesis and aerobic respiration have all of the following in common except

are processes that store energy in the form of sugar.

CAM plants perform the photosynthesis light reactions and the Calvin cycle during the

day

Compared with C3 plants, C4 plants are better adapted to....

high light intensities

Oxidation is the

loss of electrons

The general name for an assembly of pigment molecules that includes a reaction center and many accessory pigments is

photosystem

Which of the following is most likely to occur in a leaf of a CAM plant during the day?

release of CO2 from a four-carbon acid molecule

The enzyme that catalyzes the first step of the Calvin cycle is

rubisco

Plants which engage in C4 photosynthesis

shuttle CO2 as a four carbon acid from the mesophyll to the bundle sheath, and have Kranz anatomy

Which scientist was the first to propose that water is the source of oxygen produced during photosynthesis?

van Niel

During the light reactions of photosynthesis

water is split into hydrogen ions, electrons, and molecular oxygen.
