Substrate-level phosphorylation is one of the ways for the formation of ATP. In this process:
1. maximum ATP are produced in higher organisms
2. a high-energy phosphate group is transferred directly to ADP
3. chemiosmosis provides energy for phosphorylation
4. the protein ATP synthase works to add phosphate to ADP

Fats and proteins can also provide us energy. For this to happen:
1. Fats and proteins must first be converted to glucose
2. Fats and proteins must enter separate catabolic pathways of their own
3. Fats and proteins must be modified to forms that can enter the glucose metabolic pathway
4. Fats must first be converted to proteins that can enter the glucose metabolic pathway

2. reduces FAD+ to FADH2
3. oxidizes NADH to NAD+
4. reduces FADH2 to FAD+
