During chemiosmosis
ATP is synthesized when hydrogen ions move through a channel and ATP synthase
As a result of glycolysis there is a net gain of
2atp
roteone is a poison commonly added to insecticides rhodium binds tightly with one electron carrier molecules in the electron transport chain preventing electrons from passing to the next carrier molecule insects exposed to roteone will die because
They won’t be able to produce ATP
Vitamins act as

As electrons move through the mitochondrial space
The pH of the intermembrane space changes
Which of the following statements regarding the movement of electrons during cellular respiration is true

arsenic is a poison that binds to a molecule needed to build a seal coenzyme a based on this information which part of cellular respiration would be stopped if arsenic were ingested
Citric acid cycle
How do cells capture the energy released by cellular respiration
They produce ATP

Increase surface area
At the end of the citric acid cycle most of the energy is stored in
NADH
Fermentation is
How carrier molecules are regenerated when there is no oxygen
wood frogs freeze solid during the winter and then thaw in the spring as the freezing progresses blood circulation stops how would you expect the cells not being served by the circulatory system to produce ATP during this time and what by product would you expect to build up in the cells
Fermentation lactate
To obtain energy from starch and glycogen the body must begin by
Hydrolyzing both starch and glycogen to glucose
