When making bread with common yeast, the reaction starts as an aerobic process and then becomes an anaerobic process after the oxygen is spent. A baker has created a new strain of yeast which contains no cytochrome c gene and, thus, no cytochrome c protein. This will affect what the yeast strain can do to obtain energy.
What will this yeast strain do more of, compared to a normal strain?
A.
electron transport
B.
carbon dioxide production
C.
fermentation
D.
ATP synthesis
1. Oxidation is a favorable process in an aerobic environment, which is the reason cells are able to derive energy from the oxidation of macromolecules. Once carbon has been oxidized to __________, its most stable form, it can only cycle back into the organic portion of the carbon cycle through __________.
a. CH3, combustion
b. CO, reduction
c. CO2, respiration
d. CO2, photosynthesis
2.
The ultimate source of energy in our planet is sunlight. In the first stage of photosynthesis, light energy is captured in chlorophyll-containing reaction centers (PSII and PSI). What is the first step in the capture of light energy at PSII?
a. The energy carriers ATP and NADPH + H+ are synthesized.
b. CO2 reacts with the C5 sugar ribulose-1,5-bis-phosphate in the first step of the Calvin cycle.
c. Starch is synthesized.
d. H2O is photolyzed and its electrons are captured by special chlorophyll molecules.
