a chemical process that transfers energy to its surroundings

sub-cellular structures involved in aerobic cellular respiration

Aerobic cellular respiration in humans and other organisms

Combined science

Anaerobic cellular respiration in humans and other organisms

The effect of temperature on cellular respiration in small organisms: practical

Explaining the effect of temperature on the rate of cellular respiration

The effect of different substrates on cellular respiration in yeast: practical

Explaining the effect of different substrates on the rate of cellular respiration

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

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

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

Apparatus used to measure the rate of respiration in small organisms.

The factor that we change in an experiment.

The factor that we measure in an experiment.

A measure of how much change occurs per unit of time.

When bonds in an enzyme molecule break and the molecule changes shape.

Causes results to differ by different amounts due to a factor other than the independent variable (the factor we changed).

Causes measurements to differ from the true value by the same amount each time they are taken.

The substance that fits into an enzyme’s active site.

The part of an enzyme where the substrate binds.
