Question 2 is A
3 is D
6 is ATP
BIO HELP! PLEASE PLEASE! Thank you so VERY much!!?
2. Which of these is the MOST important difference between aerobic respiration and anaerobic respiration? (Points :1)
Aerobic respiration produces more ATP for a cell.
Anaerobic respiration produces more ATP for a cell.
Glycolysis occurs only during anaerobic respiration.
Glycolysis occurs in mitochondria during aerobic respiration.
3. Which process is the main source of the oxygen used in aerobic respiration? (Points :1)
the dark reaction of photosynthesis
the Krebs cycle
the light reaction of photosynthesis
the electron transport chain
4. Which of these life processes is an example of anabolic metabolism? (Points :1)
chemical digestion
passive transport
protein synthesis
cell plasmolysis
5. Which statement BEST summarizes the importance of oxygen to life on Earth? (Points :1)
Oxygen makes multicellular life on Earth possible.
Oxygen makes plant life on Earth possible.
Without oxygen, all unicellular life on Earth would die.
Without oxygen, no life would exist on Earth.
6. Which substance in a cell contains the MOST potential energy? (Points :1)
ADP
ATP
oxygen
glucose
7. The movement of hydrogen ions through a protein in a thylakoid membrane provides the energy for making ATP. Which type of energy do the hydrogen ions have? (Points :1)
chemical energy
kinetic energy
light energy
potential energy
8. Which of the following events was most likely responsible for the oxygenation of Earth’s atmosphere between two and three billion years ago? (Points :1)
the formation of carbonate rocks
the growth of the oceans
the formation of large volcanic mountains
the evolution of photosynthetic microorganisms
9. In an experiment, two aquatic snails and two sprigs of pond weed are sealed in a glass jar filled with water. How could you change the experiment to BEST test the effect of a reduction in the amount of oxygen in the environment? (Points :1)
Add more water.
Add another sprig of pond weed.
Remove one sprig of pond weed.
Remove one of the snails.
10. Which of the following could slow down the production of ATP in an animal cell? (Points :1)
removing some carbon dioxide from the cell
adding some oxygen to the cell
increasing the number of mitochondria in the cell
removing some ATP synthase enzymes from the cell

2. Aerobic respiration produces more ATP for a cell
3. the light reaction of photosynthesis
4. protein synthesis (anabolism means synethesis)
5. Without oxygen, no life would exist on Earth.
6. glucose (when one glucose molecule is processed, 36-38 ATP’s are produced)
7. kinetic energy (kinetic energy is associated with things in motion)
8. the evolution of photosynthetic microorganisms
9. Remove one sprig of pond weed
10. removing some ATP synthase enzymes from the cell (Hydrogen ions move down their concentration gradient through ATP synthase, a protein complex that captures their energy to produce ATP)
