Why generate your own practice set

Metabolism on the MCAT covers glycolysis, the citric acid cycle, oxidative phosphorylation, beta-oxidation and how hormones switch these pathways on and off. A ready-made printable sheet of MCAT metabolism practice questions is written for a generic syllabus, so it may skip the enzymes and regulatory steps your course actually covered.

Multiple-choice, true/false and short-answer formats from the same source
Explanations that show why the correct pathway step fits the question
Study in the browser on the free plan, with exports on paid plans
Works with PDFs, slides, typed notes and photos of handwritten pages

Example MCAT metabolism practice questions

Which enzyme catalyzes the committed step of glycolysis?Phosphofructokinase-1 (PFK-1), which converts fructose-6-phosphate to fructose-1,6-bisphosphate. It is the main control point because it is allosterically inhibited by ATP and citrate.

Which cofactors carry electrons from the citric acid cycle to the electron transport chain?NADH and FADH2. NADH delivers its electrons at Complex I, while FADH2 delivers them at Complex II, so FADH2 yields less ATP per molecule.

True or false: glycolysis requires oxygen to proceed.False. Glycolysis runs without oxygen, and NAD+ is regenerated by fermentation when oxygen is absent.

Which hormone stimulates glycogenolysis and gluconeogenesis in the liver during fasting?Glucagon. It raises blood glucose during fasting, while insulin has the opposite effect in the fed state.

Where does beta-oxidation of fatty acids take place in the cell?The mitochondrial matrix. The acetyl-CoA it produces then enters the citric acid cycle in the same compartment.

Generate the full set

Questions from your own material

Upload the lectures, handouts or photos of pages you already study from, and the questions follow your course's exact wording and emphasis.

Explanations for every answer

Each question comes with a reason for the correct answer, so a wrong guess becomes a short lesson on the pathway instead of a dead end.

Study pack ready to export

Study in the browser for free, or export to PDF or DOCX for printing. QTI 2.1 and Moodle XML exports are available on Pro.

How it works

Upload your metabolism material

Add a PDF, DOCX, PPTX, text file or photos of your notes. Photos are read with text recognition.

Choose the question format

Pick multiple choice, true/false or short answer. Mix formats to match the way the MCAT tests metabolism.

Practice and review the explanations

Answer each question, read the explanation, and return to the questions you missed until the pathways make sense.

Generating questions from your own notes keeps the practice tied to what you have studied. You can see which pathway each question draws from, check the explanation against your source, and repeat the questions you miss.

Start with one pathway at a time, such as glycolysis, and build up to how the pathways connect through acetyl-CoA and NADH. Short answer questions are useful for testing whether you can explain a process rather than recognize it.

Frequently asked questions

How do I study metabolism pathways for the MCAT?

Learn each pathway by its inputs, outputs, enzymes and regulation, then connect the pathways through shared intermediates such as acetyl-CoA. Practice explaining the flow of carbon and electrons aloud without looking at your notes.

How many practice questions should I do per metabolism topic?

There is no fixed number. Keep working through a topic until you can answer mixed questions on it correctly and explain why the wrong options fail.

Is DeckOwl free for MCAT practice?

The free plan includes 3 generations per month and studying in the browser, but it does not include exports. Paid plans remove the generation limit and add exports.

Which formats can I export the questions to?

Plus exports to PDF, DOCX, Anki and CSV. Pro adds QTI 2.1 and Moodle XML exports for learning management systems.
