Aerobic Respiration in Yeast Experiment

The process by which yeast cells break down glucose to release energy.

Respiration that requires oxygen.

A blue dye used as an indicator to measure respiration rate.

How fast an organism is respiring.

Warmer temperatures generally speed up the rate of respiration.

A substance that changes color to show changes in the environment.

A mixture of yeast cells in a liquid.

A solution containing glucose, used as a food source for yeast.

The time taken for the methylene blue to lose its color.

The variable deliberately changed in an experiment to observe its effect on another variable.

The variable measured and observed in relation to the independent variable.

The process by which organisms use oxygen to release energy from glucose.

The temperature at which a biochemical process, such as respiration, occurs fastest/most efficiently.

The change in shape of an enzyme's active site, preventing it from binding to its substrate and thus reducing its activity.

A dye used as an indicator in experiments measuring the rate of aerobic respiration; its colour changes in the presence of oxygen.

Measure of how quickly yeast uses oxygen to create energy.

Keeping other factors constant to ensure the only the independent variable changes the dependent variable.

The rate of aerobic respiration increases with temperature up to a certain point (optimum temperature) and then decreases because of enzyme denaturation.
