Question

making models: drawing flow charts--cellular respiration 5 parts 0.2 of 1 point 1. the horizontal lines represent covalent bonds between carbons. true false 2. the model shows that the number of carbons decreases over time. true 3. each pyruvate molecule yields one 2 - carbon acetyl coa and one co₂. true 4. the missing label for the bottom pair of arrows should be \electron transport chain.\ false 5. both the red circles and the orange circles represent carbons. true ai study tool textbook ask my instructor next

Explanation:

1. In cellular - respiration models, horizontal lines don't always represent C - C covalent bonds.
2. During cellular respiration, carbon numbers change as in pyruvate breakdown.
3. Pyruvate is converted to acetyl - CoA and CO₂ in the link reaction.
4. Without seeing the full model, we can't assume the label is "Electron transport chain".
5. In such models, different circles can represent carbon atoms.

Answer:

1. False
2. True
3. True
4. False
5. True
