Photosynthesis and Cellular Respiration

What is the net gain of ATP during glycolysis?

2

Cyanide is a powerful poison because it inhibits an enzyme in mitochondria, preventing the transfer of energy during one of the steps in cellular respiration. This poison would directly affect the production of which of the following molecules?

ATP

What is the energy molecule that is used during photosynthesis?

ATP

What step of cellular respiration produces the MOST ATP?

Aerobic Respiration

How does the amount of energy resulting from fermentation compare with that of aerobic respiration?

Aerobic respiration results in more energy.

What organism produces oxygen and what organism produces carbon dioxide.

Animals release carbon dioxide; Plants produce oxygen

Which of the following is the correct chemical formula for glucose?

C6H12O6

What stage of photosynthesis uses carbon dioxide to make glucose

Calvin Cycle

Which of the following is not a product of photosynthesis?

Carbon Dioxide

This same banana plant produces glucose from the process in the previous equation. What is the glucose being produced from? (Reactants of this process)

Carbon Dioxide and Water

What molecule do plants pull from the air that is used to make sugar?

Carbon dioxide

Which statement describes how photosynthesis and cellular respiration are interrelated?

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

What pigment molecule in plants absorbs blue and green light, making leaves appear yellow, red, and orange?

Carotenoid

What pigment molecule absorbs blue and red light to provide energy for photosynthesis?

Chlorophyll

What is the name of the organelle where photosynthesis takes place?

Chloroplast

This is one of the end products of photosynthesis. What is it?

Glucose

What is the name of the 1st step of cellular respiration?

Glycolysis

What are the three steps of cellular respiration?

Glycolysis, the Krebs cycle, and the electron transport chain.

Four identical plants are grown under different colored light bulbs. Under which color will the release of oxygen gas be the slowest?

Green

Why is a plant classified as an autotroph?

It makes its own food

From the same situation as above. What scenarios can happen that will allow the test tube that was still yellow and in the dark to turn blue?

Move the test tube into the sunlight

Two different species of bacteria are examined. Scientists find that species A always produces carbon dioxide and water during cellular respiration. Species B always produces ethyl alcohol and carbon dioxide. Which of the following explanations are true?

Only species A is aerobic

What are ways in which life is dependent on photosynthesis?

Organisms breathe in the oxygen, its sugar is used as food, and it helps reduce global warming

What is released at the end of the light dependent reactions?

Oxygen

Which of the following is not a reactant of photosynthesis?

Oxygen

Which of the following has the smallest effect on the rate of photosynthesis?

Oxygen concentration

Two test tubes were filled with a solution of bromothymol blue. A student exhaled through a straw into each tube, and the bromothymol blue turned yellow. An aquatic green plant was placed into each tube, and the tubes were corked. One tube was placed in the dark, and one was placed in direct sunlight. The yellow solution in the tube in sunlight turned blue, while the one in the dark remained yellow. Which statement best explains why the solution in the tube placed in sunlight returned to a blue color?

Oxygen was produced by photosynthesis.

When you have a banana plant in the African jungle. It is a plant that contains chlorophyll. That means it undergoes which of the following?

Photosynthesis

How is the nitrogen cycle important to plants? (Be sure to include the organism that undergoes nitrogen fixation in your answer)

Plants need it to be able to produce chlorophyll. Nitrogen-fixing bacteria contribute to the cycle and are important because they fix the nitrogen in the air so that it is safe for other living organisms. It does this by converting nitrogen in the atmosphere to ammonia and nitrates.

If you are a photosynthetic organism, what are you considered?

Producer

Plants made the oxygen in the air animals use to breathe by:

Splitting apart water molecules

The tiny mouth-like openings in leaves where gases move in and out is called?

Stomata

Which source provides the initial energy required in photosynthesis

Sunlight

How are cellular respiration and photosynthesis related, in terms of energy?

The reactants of photosynthesis are the products of cellular respiration.

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. What process is going to occur if the muscles are not able to take in enough oxygen?

The weightlifter will undergo anaerobic respiration because that allows them to make small amounts of ATP (energy) without the use of oxygen. Although it does produce energy, it produces much less than aerobic respiration.

What are the importance of cellular respiration and photosynthesis to each other?

They depend on each other; the products of cellular respiration (Carbon Dioxide and Water) are what is needed for photosynthesis. The products of photosynthesis (Glucose and Oxygen) are what is needed for cellular respiration.

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

This is because the plant cannot go through photosynthesis, releasing oxygen, if there is no sunlight; photosynthesis decreases as a plant is moved further away from a light source

Photosynthesis occurs in the membrane of which structure within a chloroplast?

Thylakoid

What is the main purpose of cellular respiration?

To break down sugars and produce carbon dioxide, water, and energy

Which process allows water to be pulled from the roots to the leaves so it can be used for photosynthesis?

Transpiration

Which is a product of the Electron Transport Chain?

Water

Which process takes place in the presence of oxygen and produces nearly 20 times as much as ATP as glycolysis alone?

aerobic respiration

What converts nitrogen gas into a usable form for plants and animals?

bacteria

Which of the following structure is where photosynthesis occurs in the cell?

chloroplast

Molecular oxygen is produced during

the light reactions of photosynthesis
