LAB REVIEW OF EXPERIMENTS - GROUP DISCUSSION
1. Explain the relative acidity of a pH = 5 vs. a pH = 7.
- A pH of 5 is 100x more acidic than a pH of 7
2. Describe 2 reasons why the water sample you tested did NOT have a pH = 7.
- Tap water contains othe

What is the connection between what an organism eats (uses as electron donor) and
breathes (uses as electron acceptor) and nutrient cycles? Are all steps in nutrient
cycles due to organisms catabolism, or are some biosyn

The first step in sulfate reduction is to activate sulfate by converting it to
adenosylphosphosulfate (APS), hydrolyzing ATP. Why is this necessary?
Hydrogen cycling is apparently used by sulfate reducers to gain par

In catabolism, are the products generally more or less ordered than the substrates?
How does this relate to energy generation and G?
The products of anabolism are cell material.
