What are the two kinds of reactions in photosynthesis?
Photolysis, Calvin Cycle
Glycolysis,Electron Transport Chain
Photolysis, Glycolysis
Calvin Cycle, Kreb's Cycle
Give the proper sequence of the three basic stages of the dark reaction:
I.RuBP regeneration
II. Carbon dioxide fixation
III. Carbon dioxide reduction
I, II, III
II, III, I
I, III, II
III, II, I
All of the following are reactants and products of photosynthesis EXCEPT:
CO2
H2O
ATP
C6H12O6
If the weather is hot and dry, the stomata will close to conserve water, so the concentration of carbon dioxide decreases in leaves, while the oxygen increases. When oxygen rises, it combines with RuBP that results to the release of carbon dioxide in the atmosphere.This wasteful process is called ________________.
Photorespiration
Phosphorylation
Glycolysis
Kreb's cycle
What organelles are involved in photosynthesis?
cristae & matrix
thylakoid & stroma
cytoplasm chlorophyll
cristae & thylakoid
Which of the following pairs is mismatched?
glycolysis-cytoplasm
photosynthesis-chloroplast
Kreb's cycle-matrix
electron transport chain-nucleus
Majority of the CO2 is released during:
Glycolysis
Citric Acid Cycle
Electron Transport Chain
Oxidative phosphorylation
The positively charged hydrogen ions that are released from the glucose during cellular respiration eventually combine with _______ ion to form ______.
another hydrogen; a gas
a carbon; carbon dioxide
an oxygen; water
a pyruvic acid; lactic acid
Anaerobic pathway that oxidize glucose to generate ATP energy by using an organic molecule as the ultimate hydrogen acceptor is called ______________.
fermentation
reduction
Kreb's Cycle
electron pumps
When skeletal muscle cells function anaerobically they accumulate the compound _____________, which causes muscle soreness.
pyruvic acid
malic acid
carbon dioxide
lactic acid
In complete accounting of all ATPs produced in aerobic respiration, there's a total of ________ ATPs: _____ from the ETC, ______ from Glycolysis, and _____ from the Kreb's Cycle.

Which of the following stages of cell respiration is an anaerobic?
Glycolysis
Preparatory Reaction
Kreb's Cycle
Electron Transport Chain
When a cell is placed in a hypertonic solution,
solute exits the cell to equalized the concentration on both sides of the membrane.
water exits the cell towards the area of lower solute concentration
water exits the cell towards the area of higher solute concentration
solute exits, water enters the cell
Which of these is NOT a lipid?
