These organisms most specifically utilize light energy to make organic molecules from inorganic molecules.
________ consume organic molecules to live.
Which of the following organisms produce organic matter from inorganic molecules?
A. photosynthetic bacteria
The equation, 6CO2 + 6H2O-->C6H12O6 + 6O2, describes a reaction that
The equation, 6CO2 + 6H2O-->C6H12O6 + 6O2, describes which of the following processes?
In what portion of the plant does photosynthesis takes place?
C. thylakoid membrane
The main structure for gas exchange in plants is called the
Which of the following statements would be most INCORRECT if there were a sudden decline in plants on Earth?
The rate of photosynthesis in existing plants would decline
Which of the following is NOT a product of the light reaction?
A new flower species has a unique photosynthetic pigment. The leaves of this plant appear to be blue-green. What wavelengths of visible light does this pigment reflect?
red and yellow
Among the different forms of electromagnetic radiation emitted by the sun, which form is visible?
Which of the following statements about chlorophyll is correct?
It reflects light in the green light spectrum
This pigment is responsible for the red-yellow coloration seen in leaves during the color change in autumn.
Which of the following is mismatched with its location?
ATP synthase; intermembrane space
Which of the following produces NADPH
light reactions alone
During the light reaction water is oxidized to form oxygen. This process
yields low-energy electrons and is needed to replace the electron lost by P680 during the light reaction.
Which of the following molecules directly converts NADP+ to NADPH?
Which of the following is FALSE when comparing the mitochondria and chloroplast?
The stroma of chloroplasts is similar to that of the mitochondrial inner-membrane space insofar as each has a higher H+ concentration relative to that of the chloroplast thylakoid lumen and the mitochondrial matrix.
During noncyclic electron flow of the light reaction, which molecule is the final acceptor of the high-energy electron?
In photosynthesis, which of the following is LEAST involved in the production of ATP?
