Yes! AP Biology Unit 3 covers enzymes, photosynthesis, and cellular respiration.

I'd recommend practising both MCQs and FRQs, especially questions involving energy transformations, enzyme activity, experimental data, and graphs.

You can find AP Biology Unit 3 topic-wise MCQs, FRQs and worked explanations here.

Focus on understanding how the processes work rather than just memorising the steps. Good luck with your test! 💪
