General Biology 1 Exam

How do the products of photosynthesis (glucose and oxygen) contribute to cellular respiration?

In what ways do the light reactions of photosynthesis and the electron transport chain in cellular respiration share similarities?

What is the role of the electron transport chain in the light-dependent reactions of photosynthesis?

How do the movement of electrons through the thylakoid membrane contribute to the formation of ATP and NADPH?

How does the Calvin cycle contribute to the formation of glucose?

What role does RuBP play in the Calvin cycle?

________________________ is the primary pigment involved in photosynthesis. Its ability to absorb light in the blue and red wavelengths and reflect green light makes it indispensable for photosynthesis. However, other pigments, such as carotenoids, play supporting roles in capturing light energy across different wavelengths, broadening the spectrum of light absorbed. Additionally, some pigments help protect plants from 2. ________________________ light, preventing damage to the chloroplasts.

3. ________________________ is the process by which cells break down glucose into 4. ________________________.

The three main stages of aerobic cellular respiration are 5. ________________________, the 6. ________________________ cycle, and the 7. ________________________ chain.

• Glycolysis

• Krebs

• Electron transport

Glycolysis occurs in the cytoplasm and breaks down glucose into pyruvate, yielding a small amount of ATP. The Krebs cycle takes place in the 8. ________________________, where pyruvate is further broken down, releasing 9. ________________________ and transferring high-energy electrons to NADH and FADH2.

• Mitochondria

• Carbon dioxide
