Question

name: ever josrias prado date: ———— photosynthesis vs. cell respiration directions: fill in the boxes of the reactants and products of both cell respiration and photosynthesis and answer the questions that follow photosynthesis: $6\text{co}_2 + 6\text{h}_2\text{o} + \text{energy} \longrightarrow \text{c}_6\text{h}_{12}\text{o}_6 + 6\text{o}_2$ respiration: $\text{c}_6\text{h}_{12}\text{o}_6 + 6\text{o}_2 \longrightarrow 6\text{co}_2 + 6\text{h}_2\text{o} + \text{energy}$

Answer:

To solve the fill - in - the - boxes for photosynthesis and cell respiration, we analyze the chemical equations and the structures (chloroplast for photosynthesis, mitochondrion for respiration):

Photosynthesis (Chloroplast)

The equation for photosynthesis is \(6CO_{2}+6H_{2}O + \text{energy}
ightarrow C_{6}H_{12}O_{6}+6O_{2}\).

• The sun - shaped icon represents the source of energy, so the box near the sun should be filled with "Sunlight (Energy)".
• The two boxes on the left (reactants entering the chloroplast) should be \(CO_{2}\) (Carbon Dioxide) and \(H_{2}O\) (Water) respectively.
• The box inside the chloroplast (the organelle) should be labeled "Chloroplast" as it is the site of photosynthesis.
• The two boxes on the right (products leaving the chloroplast) should be \(C_{6}H_{12}O_{6}\) (Glucose) and \(O_{2}\) (Oxygen) respectively.

Cell Respiration (Mitochondrion)

The equation for cell respiration is \(C_{6}H_{12}O_{6}+6O_{2}
ightarrow6CO_{2}+6H_{2}O+\text{energy}\).

• The organelle shown (with the folded membrane) is the mitochondrion, so the box inside this organelle should be labeled "Mitochondrion".
• The box with the star - shaped icon (representing energy release) should be filled with "Energy (ATP)".
• The two boxes on the left (reactants entering the mitochondrion) should be \(C_{6}H_{12}O_{6}\) (Glucose) and \(O_{2}\) (Oxygen) (we already know \(O_{2}\) is labeled on the right - hand arrow entering the mitochondrion, and glucose is the other reactant).
• The two boxes on the right (products leaving the mitochondrion) should be \(CO_{2}\) (Carbon Dioxide) and \(H_{2}O\) (Water) respectively.

Final Fills (Key Boxes):

• Near the sun (photosynthesis energy source): Sunlight (Energy)
• Chloroplast reactants (left boxes): \(CO_{2}\) (Carbon Dioxide), \(H_{2}O\) (Water)
• Chloroplast (inside the oval): Chloroplast
• Chloroplast products (right boxes): \(C_{6}H_{12}O_{6}\) (Glucose), \(O_{2}\) (Oxygen)
• Mitochondrion (inside the folded membrane): Mitochondrion
• Energy release (star - shaped): Energy (ATP)
• Mitochondrion reactants (left and the \(O_{2}\) arrow): \(C_{6}H_{12}O_{6}\) (Glucose), \(O_{2}\) (Oxygen)
• Mitochondrion products (right boxes): \(CO_{2}\) (Carbon Dioxide), \(H_{2}O\) (Water)

If we consider the most prominent boxes to fill based on the equation:

• For photosynthesis reactants (the two left boxes before chloroplast): \(CO_{2}\) and \(H_{2}O\)
• For photosynthesis products (the two right boxes after chloroplast): \(C_{6}H_{12}O_{6}\) and \(O_{2}\)
• For respiration reactants (the two boxes entering mitochondrion, one is \(O_{2}\) given, the other is \(C_{6}H_{12}O_{6}\))
• For respiration products (the two boxes leaving mitochondrion): \(CO_{2}\) and \(H_{2}O\)
• Energy source for photosynthesis: Sunlight
• Energy released in respiration: Energy (ATP)
• Organelle for photosynthesis: Chloroplast
• Organelle for respiration: Mitochondrion

If we were to summarize the key fills based on the equation labels:

• Photosynthesis:
• Reactants: \(CO_{2}\) (Carbon Dioxide), \(H_{2}O\) (Water), Energy (Sunlight)
• Organelle: Chloroplast
• Products: \(C_{6}H_{12}O_{6}\) (Glucose), \(O_{2}\) (Oxygen)
• Respiration:
• Reactants: \(C_{6}H_{12}O_{6}\) (Glucose), \(O_{2}\) (Oxygen)
• Organelle: Mitochondrion
• Products: \(CO_{2}\) (Carbon Dioxide), \(H_{2}O\) (Water), Energy (ATP)

If you want to fill the boxes in the diagram:

1. Near the sun (top left of chloroplast): Sunlight (Energy)
2. Left - most box (entering chloroplast, photosynthesis reactant): \(CO_{2}\) (Carbon Dioxide)
3. Box next to \(CO_{2}\) (entering chloroplast, photosynthesis reactant): \(H_{2}O\) (Water)
4. Box inside chloroplast: Chloroplast
5. Top - right box (leaving chloroplast, photosynthesis product): \(O_{2}\) (Oxygen)
6. Bottom - right box (leaving chloroplast, photosynthesis product): \(C_{6}H_{12}O_{6}\) (Glucose)
7. Box inside mitochondrion: Mitochondrion
8. Left - most box (entering mitochondrion, respiration reactant): \(C_{6}H_{12}O_{6}\) (Glucose)
9. Box with star (energy release): Energy (ATP)
10. Bottom - right box (leaving mitochondrion, respiration product): \(H_{2}O\) (Water)
11. Top - right box (leaving mitochondrion, respiration product): \(CO_{2}\) (Carbon Dioxide)

The answer depends on which specific box you are referring to, but the key components are as above. For example, if we take the reactants of photosynthesis (the two left boxes before chloroplast), the answers are \(CO_{2}\) (Carbon Dioxide) and \(H_{2}O\) (Water); for the products of photosynthesis (the two right boxes after chloroplast), the answers are \(C_{6}H_{12}O_{6}\) (Glucose) and \(O_{2}\) (Oxygen); for the organelle of photosynthesis, it's Chloroplast; for the organelle of respiration, it's Mitochondrion; for the energy source of photosynthesis, it's Sunlight; for the energy released in respiration, it's Energy (ATP); for the reactants of respiration, it's \(C_{6}H_{12}O_{6}\) (Glucose) and \(O_{2}\) (Oxygen); for the products of respiration, it's \(CO_{2}\) (Carbon Dioxide) and \(H_{2}O\) (Water).
