Multiple Choice

Cellular Respiration occurs in what cell organelle?

• chloroplast

• cytoplasm

• mitochondria

• animal

Multiple Choice

Which organism go through cellular respiration?

• animals

• plants

• both animals and plants

• none

Multiple Choice

Which equation represents Cellular Respiration

Multiple Choice

Which of the following is a reactant Cellular Respiration?

• Oxygen

• Carbon Dioxide

• Water

• Sunlight

Multiple Choice

Which of the following is a reactant Cellular Respiration?

• Sunlight

• CO2

• H20

• C6 H12 O6

Multiple Choice

Cellular Respiration is an aerobic process which means it requires Oxygen.

• True

• False

Multiple Choice

Where does glycolysis take place in cells?

• Cytoplasm
• Mitochondrion
• Endoplasmic Reticulum
• Ribosomes

Multiple Choice

Glycolysis results in the net gain of:

• 2 ATP
• 4 ATP
• 4 NADH
• 2 Acetyl CoA

Explanation Slide...

Glycolysis is a metabolic pathway that does not require oxygen. It is an anaerobic process that occurs in the cytoplasm of the cell, breaking down glucose to produce ATP and NAD+. Oxygen, therefore, is not a requirement for glycolysis.

Multiple Choice

Which of the following is not a requirement for glycolysis?

• Oxygen

• ATP

• NAD⁺

• Glucose

Explanation Slide...

Glycolysis is the correct answer. It is the first step in the breakdown of glucose to extract energy in the cells. It is a series of biochemical reactions that convert glucose into pyruvate and produce ATP. Other options like the Krebs cycle and Electron Transport Chain (ETC) are subsequent steps, while Lactic Acid Fermentation is a type of anaerobic respiration that also breaks down glucose, but it is not the first step.

Multiple Choice

The first step in getting energy in the cell by breaking down glucose is known as

• Krebs cycle

• ETC

• Lactic Acid Fermentation

• Glycolysis

Explanation Slide...

In the process of glycolysis, a glucose molecule is broken down and converted into two molecules of pyruvic acid. This series of reactions occur in the cytoplasm, and it is an anaerobic process. Pyruvic acid is the end product of glycolysis, while citric acid, oxaloacetic acid, and Acetyl CoA are involved in other stages of cellular respiration.

Multiple Choice

In glycolysis, glucose is converted into two molecules of _____. 

• citric acid

• oxaloacetic acid

• pyruvate

• Acetyl CoA

Multiple Select

Multiple Choice

How many ATP are produced by the Krebs Cycle per glucose?

• 0 ATP

• 1 ATP

• 2 ATP

• 3 ATP

• 4 ATP

Multiple Choice

What is the primary role of NADH and FADH₂ molecules?

• Bring glucose to the Electron Transport Chain

• Bring H with their electrons to the Electron Transport Chain

• Bring Water to the Krebs Cycle

• Bring Oxygen to the Krebs Cycle

• Calvin cycle

Multiple Choice

What is the correct equation for cellular respiration?

• 6O₂ + C₆H₁₂O₆ -> 6CO₂ + 6H₂O + Energy
• 6O₂ + C₆H₁₂O₆ + Energy -> 6CO₂ + 6H₂O
• 6CO₂ + 6H₂O -> 6O₂ + C₆H₁₂O₆ + Energy
• 6CO₂ + 6H₂O + Energy -> 6O₂ + C₆H₁₂O₆

Multiple Choice

In which way are photosynthesis and cellular respiration different?

• Cellular respiration stores ATP, while photosynthesis releases ATP.
• Cellular respiration produces oxygen, while photosynthesis uses oxygen.
• Photosynthesis releases energy, while cellular respiration stores energy.
• Photosynthesis used carbon dioxide, while cellular respiration produces carbon dioxide.
