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.
