Question

1. 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 mechanisms. compare aerobic respiration to alternative processes of glucose metabolism.

1. aerobic cellular respiration breaks the chemical bonds of glucose and oxygen molecules to form atp, water, and carbon dioxide. represent this in a chemical formula.
2. label the glucose in the above formula as either chemical or solar energy. label the atp as either chemical or solar energy. is the energy conversion in respiration \chemical → chemical,\ \chemical → solar,\ \solar → solar,\ or \solar → chemical\?
3. the atp energy made in respiration is used for cellular processes and eventually lost as heat to the atmosphere. in this process, is energy going into or out of the cell?
4. when tracking the movement of \matter,\ it is often easiest to track carbon atoms (c). circle the carbon - containing molecules in the above formula. explain what happens to the matter in respiration. (where does the matter go?)

Explanation:

Step1: Write chemical formula for aerobic respiration

The chemical formula for aerobic cellular respiration is $C_{6}H_{12}O_{6}+6O_{2}
ightarrow6CO_{2} + 6H_{2}O+ATP$.

Step2: Label energy types

Glucose is chemical - energy stored in its bonds. ATP is also chemical energy. The energy conversion in respiration is "chemical → chemical" as the chemical energy in glucose is converted into chemical energy in ATP.

Step3: Determine energy flow

The ATP energy is used for cellular processes and eventually lost as heat to the atmosphere, so energy is going out of the cell.

Step4: Track carbon - containing molecules

In the formula $C_{6}H_{12}O_{6}+6O_{2}
ightarrow6CO_{2} + 6H_{2}O+ATP$, the carbon - containing molecules are $C_{6}H_{12}O_{6}$ (glucose) and $CO_{2}$ (carbon dioxide). During respiration, the carbon in glucose is broken down and released as carbon dioxide into the atmosphere.

Answer:

1. $C_{6}H_{12}O_{6}+6O_{2}

ightarrow6CO_{2} + 6H_{2}O+ATP$

1. Glucose: Chemical energy; ATP: Chemical energy; Energy conversion: chemical → chemical
2. Out of the cell
3. Carbon - containing molecules are $C_{6}H_{12}O_{6}$ and $CO_{2}$. Carbon in glucose is released as $CO_{2}$ into the atmosphere.
