• photosynthesis
• lactic acid fermentation
• cellular respiration
• alcoholic fermentation

A weightlifter is using heavy weights in short bursts for a competition. Because his muscle cells are not able to take in enough oxygen to make very much ATP the weightlifter begins to get fatigue in his muscles. Which of the following processes is most likely going on in the muscles of the weightlifter as he competes in his event?

• As the cells run out of oxygen they switch to fermentation, which allows the cell to make small amounts of ATP in the absence of oxygen.
• As the cells run out of oxygen, they die off gradually and the weightlifter's muscles have fewer contracting muscle cells.
• The cells will never run out of oxygen if the weightlifter is breathing.
• As the cells run out of oxygen, they will continue to make the same amount of ATP, since oxygen is not required to make ATP.

Which of the following structure is where cellular respiration occurs in the cell?

• nucleus
• cytoplasm
• mitochondria
• vacuoles

Which process do the animals in the food web use to convert energy from food into ATP?

• cellular respiration
• osmosis
• photosynthesis
• transcription

A diagram representing the relationship between photosynthesis and cellular respiration is shown.
The numbered boxes in the diagram represent which of the following?

• 1 - water; 2 - nitrogen
• 1 - nitrogen; 2 - oxygen
• 1 - oxygen; 2 - carbon dioxide
• 1 - carbon dioxide; 2 – water

Which of the following equations best represents photosynthesis?

• C + O₂ + H₂O = CO₂ +HOH
• 6CO₂ + 6H₂O = C₆H₁₂O₆ + 6O₂
• 6C + 6 H₂O = C₆H₁₂O₆
• C₆H₁₂O₆ = 6CO₂ + 6H₂O

Why are there less air bubbles as the plant is place further away from the light source

• because cellular respiration decreases when there is less light
• because the light independent reaction decreases when there is less light
• because photosynthesis decreases as a plant is moved further away from a light source
• the wavelength increases as a plant is placed further away from a light source

One of the principal compounds that living things use to store energy is

• DNA
• ATP
• H20
• CO2
