An exothermic chemical process that transfers energy for life processes, using glucose as a fuel.

A product of anaerobic cellular respiration in humans that causes muscle cramps.

The amount of oxygen necessary to remove lactic acid from the body after exercise.

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

Anaerobic cellular respiration in humans and other organisms, including ATP

Biology

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.

This unit covers cellular respiration as an exothermic reaction in all cells, comparing aerobic and anaerobic processes. It explores cell structures and functions, enhanced by electron microscopy. Emphasis is on conducting experiments, analysing data, and interpreting results.

Aerobic and anaerobic cellular respiration

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

What are the uses of anaerobic cellular respiration (fermentation) 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.

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

How many molecules of ATP are produced from a molecule of glucose in anaerobic respiration?

Which chemical reactions release energy to the surroundings?

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

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

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

Which is the correct symbol equation for respiration?

True or false? Prokaryotic cells and eukaryotic cells carry out respiration.

In which two places does cellular respiration take place in eukaryotic cells?

True or false? ATP is a chemical energy store and produced through photosynthesis.
