The effect of temperature on gas production in yeast;

As the temperature gets higher, the yeast will produce more carbon dioxide, until at some point carbon dioxide production will decrease, that is when the yeast cells have become denatured due to the increase in tempmoreerature.

<h3>An experiment to show the effect of temperature on gas production in yeast.</h3><h3 />

If temperatures affect the growth of yeast and the amount of carbon dioxide gas produced then when the yeast is placed for instance in 75 degrees, the carbon dioxide levels will be than the carbon dioxide levels at room temperature (69 degrees), and 40 degrees, because heat activates the enzyme molecules to move faster

Yeast at an optimal temperature to produce the same amount of CO2 as yeast below or above it. ... Enzymes involved in yeast cell metabolism start to denature above-optimal temperatures, resulting in a decrease in both metabolic rate and CO2 production.

Explanation:

These two systems i. e. scuba diver and scuba gear interacting with each other by giving oxygen to the individual and remove carbondioxide gas from the diver. The input of this system is oxygen that is required by the diver while the output is the carbondioxide gas produced by the diver or the movement of the diver. This scuba gear is responsible for the removal of carbondioxide gas from the system. This scuba gear enable us to stay in deep water for 60 minutes.
