Cellular Respiration and Fermentation

Which process breaks down sugars to make ATP when oxygen is present?

• anaerobic respiration

• cellular respiration

• glycolysis

• photosynthesis

The part of cellular respiration in which glucose is broken down is called

• photosynthesis

• aerobic respiration.

• electron transport.

• glycolysis

Two products of the Krebs cycle are

• H2O AND CO2

• ATP and CO2.

• ATP and O2.

• ADP and H2O.

What provides the electron transport chain in cellular respiration with the energy (electrons) it needs to function?

• ATP synthase

• glycolysis

• chlorophyll

• Krebs cycle

Which of the following statements best describes cellular respiration?

• Sunlight and carbon dioxide are used to make ATP.

• ATP and oxygen are used to make sugars and starches.

• Glucose (C6H12O6) and other carbon-based molecules from food and oxygen are used to make ATP.

• ATP and carbon dioxide are used to make ADP and water.

What is the main function of the Krebs cycle?

• breaking down pyruvate molecules to form molecules of NADH and oxygen

• forming citric acid to make NADH, water, and

• producing Carbon Dioxide from broke down Glucose

• bonding coenzyme A to pyruvate

Which phrase best describes the main role of fermentation?

• converts glucose into pyruvate and NADH

• produces lactic acid to counteract an oxygen deficit

• allows glycolysis to continue making a small amount of ATP

• allowing anaerobic production of ADP

Which phrase about fermentation is correct?

• takes place without oxygen

• uses electron transport chain

• only occurs in bacteria

• is an aerobic process

Which end product of fermentation causes the burning feeling in muscles that are working hard?

• carbon dioxide

• pyruvate

• alcohol

• lactic acid

Which end product of alcoholic fermentation is important in the baking industry that makes breads fluffy and squishy?

• lactic acid

• carbon dioxide

• ATP molecules

• alcohol
