PHOTOSYNTHESIS AND CELLULAR RESPIRATION

Here are Knowt-style flashcards covering everything you need to know for the Living Environment Regents on Photosynthesis and Cellular Respiration—no fluff, no skipped facts, just what matters.

📘 PHOTOSYNTHESIS FLASHCARDS

1. What is the formula for photosynthesis?

Carbon dioxide + water + sunlight → glucose + oxygen

6CO₂ + 6H₂O + light → C₆H₁₂O₆ + 6O₂

2. Where does photosynthesis take place?

In the chloroplasts of plant cells.

3. What pigment captures light energy?

Chlorophyll—it gives plants their green color.

4. What organisms perform photosynthesis?

Plants, algae, and some bacteria (autotrophs).

5. Why is photosynthesis important?

It produces glucose for energy and oxygen for aerobic life.

6. What are the raw materials (reactants) of photosynthesis?

Carbon dioxide and water

7. What are the products of photosynthesis?

Glucose (sugar) and oxygen

8. During what time does photosynthesis occur?

Only during daylight, because it needs sunlight.

9. How does carbon dioxide enter the plant?

Through the stomata in the leaves.

10. What is the main purpose of photosynthesis?

To make glucose (C₆H₁₂O₆) for the plant’s energy.

🔋 CELLULAR RESPIRATION FLASHCARDS

11. What is the formula for cellular respiration?

Glucose + oxygen → carbon dioxide + water + energy (ATP)

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP

12. Where does cellular respiration happen?

In the mitochondria of all eukaryotic cells.

13. What is the purpose of cellular respiration?

To convert glucose into ATP, the usable energy for cells.

14. What are the two types of cellular respiration?

Aerobic (uses oxygen) and anaerobic (does not use oxygen).

15. Which type of respiration makes more energy?

Aerobic respiration makes 36 ATP per glucose.

Anaerobic makes only 2 ATP.

16. What are the products of aerobic respiration?

Carbon dioxide, water, and 36 ATP

17. What are the products of anaerobic respiration in humans?

Lactic acid and 2 ATP — happens in muscles during intense activity.

18. What are the products of anaerobic respiration in yeast?

Alcohol, CO₂, and 2 ATP — used in baking and brewing.

19. What organisms do cellular respiration?

All organisms—plants, animals, fungi, bacteria, etc.

20. What process is the opposite of photosynthesis?

Cellular respiration — it breaks down glucose, not builds it.
