Suppose that the levels of Pi inside of a cell droppeddramatically. How would this affect glycolysis and why? Glyceraldehyde 3-phosphate dehydrogenase catalyzes thereaction of glyceraldehyde-3-phosphate + NAD+ + Pi ®1,3-bisphosphoglyceric acid + NADH + H2O. Suppose that theproduct of the reaction was 3-phosphoglyceric acid instead of1,3-bisphosphoglyceric acid. How would this […]

The purpose of this activity is to demonstrate that animals and plants depend upon each other for survival. To get started, think of “Photosynthesis: Acquiring Energy from the Sun”. As you read start thinking about how plants consume carbon dioxide (an animal waste product) and release oxygen (a plant waste […]
