Respiration and Photosynthesis

When ATP breaks down to ADP and Pi, 

• many enzymes are destroyed
• high temperatures are generated
• energy is released which can then be used by the cell
• hydrogen and carbon dioxide are produced as wastes

Which of the following is not part of the ATP molecule?

• ribose
• adenine
• thymine
• phosphate

In cellular respiration, production of CO2

• results from the breakdown of ATP
• occurs in greatest quantities during the Kreb's Cycle
• occurs each time an ATP is produced
• takes place only in glycolysis

Fermentation of Glucose results in

• the formation of nucleis acids from nucleotides
• high energy yield of nearly 36 molecules of ATP for each glucose molecule
• energy being released as the result of oxidation
• a low energy yield of about 2 molecules of ATP to each glucose molecule.

The efficiency of energy released from glucose during anaerobic respiration is about

• 62.5|%
• 2.4%
• 100%
• 80%

Within the cell, the site of aerobic respiration is the

• nucleolus
• golgi bodies
• ribosomes
• mitochondria

Aerobic respiration requires the presence of 

• carbon dioxide
• water
• oxygen
• hydrogen

Glycolysis is best represented by

• glucose---> pyruvic acid---> citric acid
• glucose ---> 2 pyruvic acid + 2 ATP + 4 NADH
• glucose---> CO2 and O2
• CO2 +H2O---> C6H12O6

The purpose of cellular respiration is to transfer energy from

• ATP to glucose
• enzymes to CO2
• glucose to ATP
• glucose to CO2

Anaerobic respiration in humans is most often carried out in

• heart tissue
• liver tissue
• brain tissue
• muscle tissue
