Photosynthesis is the process in which green plants use sunlight to make their own food. Photosynthesis is necessary for life on Earth. Which of these would lead to a lower rate of photosynthesis in a plant?

WHAT DOES PHOTOSYNTHESIS NEED?

Multiple Choice

Photosynthesis is the process in which green plants use sunlight to make their own food. Photosynthesis is necessary for life on Earth. Which of these would lead to a lower rate of photosynthesis in a plant?

• An increase in the amount of oxygen in the air

• A decrease in the amount of oxygen in the air

• An increase in the amount of carbon dioxide in the air

• A decrease in the amount of carbon dioxide in the air

Multiple Choice

In the figure shown, why might the candle in jar A burn longer than the candle in jar B?

• Carbon dioxide produced by the plant allows the candle to burn longer.

• Chlorophyll produced by the plant allows the candle to burn longer.

• Glucose produced by the plant allows the candle to burn longer.

• Oxygen produced by the plant allows the candle to burn longer

Multiple Choice

The equation below illustrates the process of cell respiration. According to the equation, which of the following occurs during this process?

C6H12O6 + 6O2 → 6CO2 + 6H20 + Energy (ATP)

• Carbon dioxide, water, and energy are produced when glucose combines with oxygen.

• Oxygen combines with water to make glucose and carbon dioxide.

• Water combines with oxygen to make carbon dioxide.

• Glucose is produced during this process.

Multiple Choice

The graph below shows the change in blood glucose level during prolonged exercise.

Which of the following statements explains the change in blood glucose level shown in the graph?

• Glucose was broken down to produce ATP for energy.

• Glucose diffused from muscle cells into the bloodstream.

• Proteins combined with glucose  to produce ADP for energy.

• Polysaccharides were made from glucose in metabolic pathways.

Multiple Choice

The diagram below shows the relationship between photosynthesis and cellular respiration and the organelles in which they occur. Which statement describes how photosynthesis and cellular respiration are interrelated?

• Oxygen is produced during cellular respiration and stored during photosynthesis.

• Carbon dioxide and water released by cellular respiration are used in photosynthesis.

• Photosynthesis releases the energy that is stored during the process of cellular respiration.

• Glucose is used during cellular respiration to produce food that is broken down during photosynthesis.

Multiple Choice

Which of the following is one of the ways that cellular respiration and photosynthesis are opposite processes?

• Photosynthesis releases energy and cellular respiration stores energy

• Photosynthesis removes carbon dioxide from the atmosphere, cellular respiration puts it back

• Photosynthesis removes oxygen from the atmosphere, cellular respiration puts it back

• Photosynthesis consumes glucose, cellular respiration produces glucose

Multiple Choice

The diagram below shows the relationship between photosynthesis and cellular respiration and the organelles in which they occur. Which statement describes which organelles are responsible for each reaction?

• Chloroplasts use energy from the sun to generate carbon dioxide and water.

• Mitochondria and chloroplasts both require sunlight and both perform photosynthesis.

• Carbon dioxide and water released by the mitochondria are used by the chloroplast to make glucose and oxygen.

• Glucose is used by the chloroplast to generate ATP, and ATP is released from an organism as a waste product.

Multiple Choice

What is one way in which photosynthesis and cellular respiration are different?

• Cellular respiration stores ATP, while photosynthesis releases ATP.

• Cellular respiration produces oxygen, while photosynthesis uses oxygen.

• Photosynthesis stores energy, while cellular respiration releases energy.

• Photosynthesis produces carbon dioxide, while cellular respiration uses carbon dioxide.

Multiple Choice

Yeast cells can utilize both aerobic and anaerobic respiration.  Which of the following best explains why yeast cells preferentially utilize aerobic respiration when oxygen is present in the environment?

• Glucose levels are reduced under anaerobic conditions.

• The yield of energy is greater using aerobic respiration.

• Aerobic conditions are more common than anaerobic conditions.

• The end products of anaerobic respiration are toxic

Multiple Choice

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 anaerobic respiration, 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.

Multiple Choice

Which statement best describes the way that an adenosine diphosphate (ADP) molecule becomes an adenosine triphosphate (ATP) molecule in the human body?

• Energy from food is used to attach a phosphate molecule to an ADP molecule to form ATP.

• Protein causes phosphate molecules to bind to sugars and form ATP.

• Ionized oxygen in cells causes sugars and phosphate molecules to form ATP.

• Water breaks down ADP molecules which form into ATP molecules over time.

Multiple Choice

ATP and ADP both play a role in cellular reactions involving energy. How are these two molecules related?

• Adding a phosphate group to ATP produces ADP and releases energy.

• Adding a phosphate group to ADP produces ATP and releases energy.

• ADP breaks down to produce ATP and a phosphate group, releasing energy.

• ATP breaks down to produce ADP and a phosphate group, releasing energy
