Which of the following are produced during the Calvin cycle? - gylceraldehyde 3 phosphate, ADP, NADP+
Global warming due to the greenhouse effect may be - moderated by photosynthesis, which removes
carbon dioxide form the atmosphere
Oxidation is the _____, and reduction is the________. - loss of electrons; gain of electrons
During which stage of meiosis do synapsis and crossing over occur - Prophase I
The enzymes of the citric acid cycle are located in the - matrix of the mitochondria
Eukaryotic cells spend most of their cell cycle in which phase? - Interphase
What is the basic difference between exergonic and endergonic reactions? - exergonic reactions release
energy; endergonic reactions absorb it.
As a result of glycolysis there is a net gain of ______ ATP(s). - 2
Certain cells that line the stomach synthesize a digestive enzyme and secrete it into the stomach. This
enzyme is a protein. Which of the following processes could be responsible for its secretion? - exocytosis
A child is brought to the hospital with a fever of 107*F. Doctors immediately order and ice bath to lower
the child's temperature. Which of the following statements offers the most logical explanation for this
action? - elevated body temperatures may denature enzymes. This would interfere with the cell's
abilities to catalyze various reactions.
In photosynthesis, the chemiosmotic production of ATP - is similar to the production of ATP in
mitochondria
, Which of the following statements regarding the cell cycle control system is false? - the cell cycle control
system operates independently of the growth factors
the addition of oxygen instead of carbon dioxide to RuBP results in - photorespiration
In most green plants, chloroplasts are - concentrated in mesophyll cells
Rotenone is a poison commonly added to insecticides. Rotenone binds tightly with one of the electron
carrier molecules in the electron transport chain, preventing electrons from passing to the next carrier
molecule. Insects exposed to rotenone will die because - they will no longer be able to produce
adequate amounts of ATP
Oxygen crosses a plasma membrane by - passive transport
At the start of mitotic anaphase, - the centromeres of each chromosome are pulled apart
When an organism such as yeast lives by fermentation, it converts the pyruvate from glycolysis into a
different compound, such as alcohol. Why doesn't it secrete the pyruvate directly? - The conversion is
needed to regenerate the molecules, such as NAD+, needed for glycolysis
According to_______, energy cannot be created or destroyed. - the first law of thermodynamics
Which of the following statements regarding membrane protein function is false? - membrane proteins
transfer genetic information to the cytoplasm
In C3 plants, the light reactions of photosynthesis occur in the__________, while the Calvin cycle occurs
in the________. - thylakoid membranes, stroma
Which of the following options lists the stages in cellular respiration in the correct order? - glycolysis, the
citric acid cycle, and oxidative phosphorylation
