What three things does a plant need to perform photosynthesis?
Water, carbon dioxide, sunlight.
Where does photosynthesis occur?
Chloroplasts.
What is the main purpose of cellular respiration?
To produce ATP.
What is the main function of carbohydrates?
Quick energy
How does breathing help maintain homeostasis?
Removes CO₂ and brings in O₂ for respiration.
What two major products are created during photosynthesis?
Glucose and oxygen.
What is the main purpose of the light-dependent reactions?
Capture sunlight and produce ATP & NADPH
What molecule is broken down during glycolysis?
Glucose
What are the monomers of proteins?
Amino acids
Which hormone lowers blood sugar after eating?
Insulin.
What structure on the leaf allows CO₂ to enter and O₂ to exit?
Stomata.
What does the Calvin Cycle produce?
Glucose.
Name ANY two products of the Krebs Cycle.
CO₂, NADH, FADH₂, ATP (any two).
Name one function of lipids.
Long-term energy storage, insulation, cell membranes formation/structure
How does ATP help maintain homeostasis?
Powers cellular processes that keep the body stable.
What form of energy powers photosynthesis?
Light energy from the sun.
What pigment absorbs sunlight?
Chlorophyll.
Where does the electron transport chain occur?
Inner mitochondrial membrane.
What is the function of nucleic acids?
Store genetic information.
How does sweating help maintain homeostasis?
Cools the body to maintain temperature.
State the full balanced equation for photosynthesis.
6CO₂ + 6H₂O + light → C₆H₁₂O₆ + 6O₂.
What molecule transfers energy from the light reactions to the Calvin Cycle?
ATP
Which stage produces the most ATP?
Electron Transport Chain.
Match each macromolecule to its monomer:
Carbs, Proteins, Lipids, Nucleic Acids.
Carbs → Monosaccharides
Proteins → Amino acids
Lipids → Fatty acids
Nucleic acids → Nucleotides
Explain how photosynthesis in plants and respiration in humans work together to maintain homeostasis.
Plants produce oxygen and glucose; humans use both for respiration and return CO₂ to plants.
