Question

1. aerobic cellular respiration breaks the chemical bonds of glucose and oxygen molecules to
2. when tracking the movement of \matter,\ it is often easiest to track carbon atoms (c). circle

the carbon - containing molecules in the above formula. where does the matter that makes up a
plant come from?
ls1.9) create a model of aerobic respiration demonstrating flow of matter and energy out of a
cell. use the model to explain energy transfer in organisms. compare aerobic respiration to
alternative processes of glucose metabolism.

Explanation:

Step1: Understand aerobic respiration

Aerobic respiration in cells uses glucose and oxygen to produce energy, carbon - dioxide and water. The general formula is $C_6H_{12}O_6+6O_2
ightarrow6CO_2 + 6H_2O+\text{energy}$.

Step2: Track carbon atoms

In plants, carbon atoms in glucose come from carbon - dioxide absorbed from the atmosphere during photosynthesis. During aerobic respiration, the carbon atoms in glucose are released as carbon - dioxide back into the atmosphere.

Step3: Compare with alternative processes

Alternative processes like anaerobic respiration (fermentation) produce different end - products (e.g., ethanol or lactic acid) with different energy yields compared to aerobic respiration. In anaerobic respiration, the breakdown of glucose is incomplete, and less energy is released.

Answer:

The carbon atoms in glucose used in aerobic respiration come from carbon - dioxide absorbed by plants during photosynthesis. When glucose is broken down in aerobic respiration, the carbon atoms are released as carbon - dioxide back into the atmosphere. Alternative processes like anaerobic respiration have different end - products and energy yields compared to aerobic respiration.
