Question

the diagram models how energy flows through the chemical reactions of cellular respiration. move the molecules of the chemical reactions to the correct boxes.
molecules entering the body
bonds in molecules break
energy is transferred
new compounds form
molecules leaving the body
molecules used by the body
food molecules that store energy
water molecules
oxygen molecules
carbon dioxide molecules
molecules that transport energy

Explanation:

Step1: Analyze Molecules Entering

Food molecules (store energy) and oxygen molecules enter the body for cellular respiration. So "Molecules entering the body" boxes get "Food molecules that store energy" and "Oxygen molecules".

Step2: Analyze Reaction Steps

• "Bonds in molecules break": Food molecules (like glucose) have bonds broken, releasing energy. So connect to "Food molecules that store energy".
• "Energy is transferred": Energy from broken bonds is transferred (e.g., to ATP). Molecules that transport energy (like ATP) would relate, but here the input for energy transfer is the broken food molecules.
• "New compounds form": Cellular respiration produces CO₂ and H₂O, so new compounds are CO₂ and H₂O.

Step3: Analyze Molecules Leaving/Used

• "Molecules leaving the body": Carbon dioxide and water molecules (products of respiration) leave.
• "Molecules used by the body": The energy - transporting molecules (from energy transfer) are used, and also, the process uses oxygen (but oxygen is entering, used in reaction). Wait, re - align:
• Molecules entering: Food (store energy) and Oxygen.
• Bonds break: Food molecules (their bonds break).
• Energy transferred: Energy goes to molecules that transport energy.
• New compounds: Carbon dioxide and Water.
• Molecules leaving: Carbon dioxide and Water.
• Molecules used by the body: Molecules that transport energy (from energy transfer) and the food molecules are used (broken down) and oxygen is used in the reaction.

Now, mapping:

• Molecules entering the body: Food molecules that store energy, Oxygen molecules.
• Bonds in molecules break: Food molecules that store energy (their bonds break).
• Energy is transferred: Molecules that transport energy (the energy from broken food bonds is transferred to these).
• New compounds form: Carbon dioxide molecules, Water molecules.
• Molecules leaving the body: Carbon dioxide molecules, Water molecules.
• Molecules used by the body: Molecules that transport energy (used to power cell processes), Food molecules (used as fuel), Oxygen molecules (used in respiration).

Answer:

• Molecules entering the body: Food molecules that store energy, Oxygen molecules.
• Bonds in molecules break: Food molecules that store energy.
• Energy is transferred: Molecules that transport energy.
• New compounds form: Carbon dioxide molecules, Water molecules.
• Molecules leaving the body: Carbon dioxide molecules, Water molecules.
• Molecules used by the body: Molecules that transport energy, Food molecules that store energy, Oxygen molecules.
