CETR-CELL PROCESSES

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:

• CO_2

• 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
