Students have asked these similar questions
High energy electrons are used to produce ATP by:
a) Creating an electrochemical gradient
b) Pumping protons into a limited space as stored energy
c) An enzyme that couples cation movement to phosphorylation of ADP
d) The Chemiosmotic mechanism
e) All of the above
Yeast are facultative anaerobic organisms that can make ATP by aerobic respiration if
oxygen is present, but are also capable of switching to fermentation under anaerobic
conditions. For thousands of years, humans have used yeast, such as
Saccharomyces cervesisiae, to ferment grapes (starch sugar) to make wine (alcoholic
beverage). Four batches of wine were made following the contents and conditions
listed in the table below,
