Title: How does temperature change the pH of yeast during respiration? Post by: gianmaranon on Dec 13, 2015 I don't really understand how temperature affects the pH of yeast during respiration :/
Hopefully someone could explain to me. Thanks! I know that temperature change the shape of enzymes active site due to denaturing. And pH affects the shape of proteins. In the case of fermentation a collection of enzymes is responsible for the metabolic processes that occur. But I can't get my head around how the krebs cycle and link reaction are involved. Title: Re: How does temperature change the pH of yeast during respiration? Post by: dtimmons95 on Dec 13, 2015 pH is defined as negative logarithm of hydrogen ion concentration. It varies from 1 to 14. 1 to 6.9 is acidic and 7.1 to 14 alkaline. 1 is highest acidic and 14 is highest alkaline. 7 is neutral, pH is measured by specific sensors/electrodes and at room temperature along with proper calibrations. Therefore, when pH is measured at room temperature, there is no direct correlation between pH and temperature.

Well since the product of respiration is CO2, it will dissolve in water to give carbonic acid which will make the the water acidic? I guess the higher the temperature the more/faster CO2 is produced as a waste roduct? |
