Test-taking note: When answering open-ended questions like all the questions on this exam consider the point value of the question in the context of the entire exam. Many times, when an instructor values an open-ended question with 5-points they are expecting an answer that provides 5 reasons. The recommendation is to list 5 differences in complete sentences and provide a more detailed explanation of one of the 5 differences. 1. How do chloroplasts and mitochondria differ? (5 points). Remember; there are five total differences that need to be listed and two specific points I will be looking for 2. How do photochemical reactions (light-capturing reactions in photosynthesis) compare with electron transport in cellular respiration? What is similar? What is different? (5 points) 3. What are the primary components of the photochemical reactions and how do they support photosynthesis? List 5 components (2.5 points) and explain one of the components in further detail (2.5 points). 4. What are the results of the thermochemical reactions of the Calvin-Benson cycle (5 points). Thermochemical reactions are where heat flows across the boundaries of a system undergoing a change. Identify the 3-steps of the cycle; then explain 2 more important aspects of the cycle. 5. How does the Calvin cycle compare to glycolysis and the Kreb's cycle? (5 points). Another words how are they similar and how are they different? 6. How do glycolysis and the Kreb's cycle provide resources for electron transport? (5 points). 7. What happens to cellular respiration under anaerobic conditions? (5 points). In muscle cells (2.5) and in yeast (2.5)

Explanation / Answer

Mitochondria

Chloroplast

Rod shaped

Contains cristae, folds of inner membrane

Lens-shaped

Contains stroma, thylakoids and grana

Does not contain photosynthetic pigments

Found in all cells, plant and animal

Contains photosynthetic pigments

Only found in plant cells

Involved in aerobic respiration, it uses oxygen

Involved in photosynthesis- it produces oxygen

Differences:

Photochemical reactions in photosynthesis

Electron transport in respiration

Similarities:
