KE REVIEW ~ UNIT 3

20 questions

9th - 12th Grade

Biology

KE REVIEW ~ UNIT 3 is a Grade 9–12 Biology worksheet that reviews how ATP, photosynthesis, and cellular respiration manage and transform energy in cells. Students answer multiple-choice questions about ATP and ADP energy storage, the reactants and products of photosynthesis and respiration, the relationship between the two processes, and the roles of chloroplasts and mitochondria. The worksheet also connects ATP to cellular work, including cilia movement and active transport against a concentration gradient. This free printable worksheet includes 20 multiple-choice questions designed to check understanding and help students distinguish related biological processes, energy conversions, organelle functions, and environmental effects such as changes in oxygen and carbon dioxide. It works well as a unit review, formative assessment, independent practice, or test-preparation activity for secondary Biology students. A complete answer key is included so teachers can quickly check responses and identify concepts that need further instruction.

FAQs

What does the KE REVIEW ~ UNIT 3 worksheet cover?

This 20-question multiple-choice Biology review covers how ATP and ADP relate to cellular energy, how photosynthesis and cellular respiration use and produce materials, and how energy moves through these processes. Students also apply the concepts to organelles, ATP-powered cilia movement and active transport, chloroplast function, and changes in environmental oxygen and carbon dioxide.

How can I use this worksheet to teach ATP, photosynthesis, and cellular respiration?

Introduce the review by having students compare the reactants, products, and energy transformations of photosynthesis and cellular respiration. Then use the multiple-choice items to prompt explanations: ask students why ATP is needed for active transport or cilia movement, why bacteria do not use mitochondria for respiration, and how fewer plants would affect atmospheric gases. Review the answer choices afterward to address reasoning, not just letter selection.

What mistakes should I watch for when students complete this worksheet?

Students may confuse the reactants and products of photosynthesis and cellular respiration, especially carbon dioxide, oxygen, water, and glucose. They may also reverse the energy relationship between ATP and ADP, treat mitochondria as the site of respiration in bacteria, or confuse chloroplasts with mitochondria when identifying energy transformations. In diagram-based questions, check that students recognize ATP as the energy source for movement against a concentration gradient.

How do I assign and grade this worksheet?

The KE REVIEW ~ UNIT 3 worksheet is available as a printable PDF and as a digital quiz on Wayground, and it includes a complete answer key. You can grade printable submissions by scanning student work with the Wayground for Teachers app, or review responses from the digital quiz. The printable format can also support schools that are reducing screen time.

How can I differentiate this ATP and cellular respiration review worksheet?

Use the worksheet’s Advanced Settings to adjust font spacing and font size so the 20 multiple-choice questions are easier to read. You can also apply a dyslexia-friendly font or translate the worksheet into another language, while keeping the ATP, photosynthesis, cellular respiration, and energy-transformation content intact.
