Bioenergetics and Thermodynamics

What this unit covers

This unit sits in the strand Enzymes, Coenzymes and Bioenergetics, within Biochemistry. The resources follow a clear path: how energy is stored and moved, how reactions are judged by free energy, and how cells turn food into ATP.

Start with the basics

Begin with the mind maps Bioenergetics 1. and Bioenenergetics 2. The first explains how the delta G of a reaction depends on reactant and product concentrations, so the direction of a reaction can change with conditions. The second looks at high energy phosphate compounds and the free energy released when they are broken down. The flashcard deck Biological energy asks how energy can be stored and asks you to describe the structure of adenosine triphosphate.

Move on to oxidative phosphorylation

Many of the listed decks focus on this topic. Work through them in this order:

1. Oxidative Phosphorylation for electron carriers, ubiquinone, cytochrome C, Complexes I to III and the Q cycle.
2. Lectures 29+30 (Oxidative phosphorylation) for where it occurs and what is oxidised and reduced.
3. Lectures 31+32 (Oxidative phosphorylation) for the chemiosmotic hypothesis and how ATP synthase works.

The mind map Electron Transport & Coupled Oxidative Phosphorylation pulls the structure and the flow of electrons into one view.

Use quizzes and maps together

Read a map first, then test yourself. The quiz Biochemistry MCQs Exam 2- PMU 2nd Year covers oxidoreductases and the enzymes involved in energy formation. Note which questions you miss, go back to the matching map, and then retest. Teachers can set a deck or quiz as ready-made revision material.

Make it your own

Pick the topic you find hardest, open one resource, and then write your own flashcards or map to match it.
