Not Graded — Teacher Feedback Only
Purpose: Identify gaps from SBI3U (cells, basic macromolecules, transport) before starting Unit 1. You receive descriptive feedback, not a grade. Be honest about what is unclear.
Question 1 Prereq · Cells
[3 marks]
Identify which organelle is responsible for: (a) protein synthesis, (b) ATP generation, (c) lipid synthesis. State whether each is found in eukaryotes only or in both prokaryotes and eukaryotes.
Question 2 Prereq · Macromolecules
[4 marks]
Match each macromolecule (carbohydrate, lipid, protein, nucleic acid) with one biological function and one example monomer.
Question 3 Prereq · Bonding
[3 marks]
Explain the difference between a hydrogen bond and a covalent bond. Give one biological example where each is critical.
Question 4 Prereq · Transport
[3 marks]
Describe what happens to an animal cell placed in (a) hypertonic, (b) isotonic, (c) hypotonic solution. Use the term osmosis in your answer.
Question 5 Skills · Lab
[3 marks]
In a catalase enzyme lab, identify one independent variable, one dependent variable, and one controlled variable that you would use to test the effect of pH on activity.
Question 6 Knowledge
[3 marks]
A condensation (dehydration) reaction joins two glucose molecules. Name the type of bond formed, the by-product released, and the resulting disaccharide.
Question 7 Reflection
[ungraded]
Which Unit 1 topic do you feel least confident about: macromolecule structure, enzyme kinetics, or membrane transport? Explain what specifically is unclear.
Teacher Feedback
Your teacher will provide descriptive feedback after reviewing your responses.
