anaerobic cellular respiration in yeast that produces ethanol (a type of alcohol) and carbon dioxide gas

Anaerobic cellular respiration in humans and other organisms

Combined science

Pupils will learn how substances essential for chemical reactions, and the products of the reactions, are transported into, around and out of plants, and about factors affecting the rate of water uptake by a plant.

Pupils learned about photosynthesis in producers, including a two-stage model of the process and the requirements and products of each stage.

Aerobic and anaerobic cellular respiration

True or false? Anaerobic respiration takes place in the mitochondria of cells.

glucose + oxygen --> water + carbon dioxide

glucose + carbon dioxide --> water + ethanol

What is the correct word equation for anaerobic respiration in yeast?

Anaerobic cellular respiration releases more energy than aerobic respiration.

Anaerobic respiration takes place when there is an excess of carbon dioxide.

Anaerobic cellular respiration releases energy quicker.

Lactic acid is produced by aerobic cellular respiration.

Anaerobic cellular respiration produces ethanol in plants and microorganisms.

Which of the following are true about anaerobic respiration?

C$$_6$$H$$_{12}$$O$$_6$$ --> 2C$$_3$$H$$_6$$O$$_3$$

C$$_6$$H$$_{12}$$O$$_6$$ --> C$$_2$$H$$_5$$OH + 6CO$$_2$$ 

Match the symbol equation to its description.

Oxygen debt is the amount of oxygen necessary to remove {{}} from the body after exercise.

What are the uses of anaerobic cellular respiration (fermentation) in yeast?

Which chemical reactions release energy to the surroundings?

6O $$_2$$ + C$$_6$$H$$_6$$O$$_6$$ --> 3H$$_2$$O + 6CO$$_2$$

6O $$_2$$ + C$$_6$$H$$_{12}$$O$$_6$$ --> 6H$$_2$$O + 6CO$$_2$$

6O $$_2$$ + C$$_6$$H$$_6$$O$$_6$$ --> 12H$$_2$$O + 6CO$$_2$$
