Cellular Energetics

A student is collecting the gas given off from a plant in bright sunlight at a temperature of 27°C. The gas being collected is probably ________.

• oxygen
• carbon dioxide
• ATP
• glucose

How would the concentration of CO₂ in water affect photosynthesis?

• The higher the CO₂, the greater the rate
• The higher the CO₂, the lower the rate
• CO₂ concentration doesn't affect photosynthesis
• a greater rate of photosynthesis causes higher CO₂ concentrations 

How would light intensity generally affect the rate of photosynthesis?

• Increases the rate, up to a point
• Increases the rate
• Decreases the rate
• No relationship to the rate

Which conclusion best matches the trends shown on the graph?

• Bean plants produce more ATP than corn plants.
• Corn plants require more oxygen than bean plants.
• Corn plants release more carbon dioxide than bean plants.
• Corn plants produce sugars at a faster rate than bean plants.

In green plants, the primary function of the Calvin cycle is to

• Use ATP to release carbon

• Split water to release oxygen.

• Construct sugar from carbon dioxide.

• Use NADPH to release carbon

Glucose --> CO2 + Lactic Acid OR Alcohol + 2 ATP

• aerobic

• anaerobic

• both

The CO₂ you breathe out comes out of which process?

• Glycolysis

• lactic acid fermentation

• Kreb's Cycle

What is the ATP net yield of glycolysis?

• 2 ATP

• 6 ATP

• 4 ATP

• 1 ATP

What is made at the end of glycolysis?

• Carbon dioxide

• FADH2

• Pyruvate

• Water

Cell respiration is aerobic because...

• It is used to gives cell the energy needed to work.

• It produces oxygen gas in the electron transport chain

• It uses oxygen gas in the electron transport chain.

• It produces water at the end of the electron transport chain.
