About this resource
This quiz comprehensively covers cellular energetics, the central topic of AP Biology Unit 3, and is appropriately designed for 11th-12th grade students enrolled in Advanced Placement Biology. The questions systematically examine three interconnected areas: enzyme structure and function, cellular respiration, and photosynthesis. Students must demonstrate understanding of complex biochemical processes including enzyme kinetics, competitive and noncompetitive inhibition, protein denaturation, thermodynamic principles like energy coupling, and the intricate details of metabolic pathways. The quiz requires students to analyze molecular-level interactions, trace electron flow through transport chains, identify cellular compartments where specific reactions occur, and understand how cells harness and transform energy. Mastery demands knowledge of chemical structures, metabolic intermediates, and the ability to connect molecular events to broader biological principles governing cellular energy transformation. Created by Tiffany Jones, a Biology teacher in the US who teaches grades 9-12. This quiz serves as an excellent formative assessment tool to gauge student understanding before the AP Biology exam, and can be effectively used as a unit review, homework assignment, or warm-up activity to reinforce key concepts. The questions directly align with AP Biology learning objectives and can help students identify knowledge gaps in cellular energetics before moving to subsequent units. Teachers can use this quiz to guide instruction by identifying which concepts need additional reinforcement, whether students struggle more with photosynthesis versus cellular respiration, or if enzyme function requires deeper exploration. The quiz format mirrors AP Biology multiple-choice questions, providing valuable practice with the analytical thinking and content application students need for success on the College Board exam, supporting standards AP.BIO-2.A, AP.BIO-2.B, AP.BIO-3.A, and AP.BIO-3.D.

MULTIPLE CHOICE QUESTION
30 sec • 1 pt
Describe why an increase in temperature increases the rate of the reaction.
increase in temperature increases the speed/kinetic energy of particles
increase in temperature activates more enzyme to increase the rate
increase in temperature results in increase in substrate available
increase in temperature allows for a tighter fit in the active site
