I have a bio quiz on Monday and I'm working through the study guide. A few things I'm having difficulty remembering and finding in my book are: How do H^+ gradients create potential energy?

What is oxygen's role in electron transport phosphorylation, and why is the production of metabolic water so important?

Where in the cell do transcription and translation occur?

How can different types of mutation affect a protein sequence?

Great succinct + accurate answer!
