Question

a. explain how photosynthesis and cellular respiration are related. make sure to include the chemical equations and refer to those in your answer. b. if you had an unknown organism and wanted to determine if it was using photosynthesis or cellular respiration how could you do that? use lesson 4 to help you answer this question. you must also provide a reference to a lesson page that supports your answer in one of the following ways:. as explained in lesson 2 page 6. an electron is a negative a particle (lesson 2 page 6) the lesson reference is required in order to receive any credit.

Explanation:

A. Photosynthesis and cellular respiration are complementary processes. The chemical equation for photosynthesis is $6CO_{2}+6H_{2}O + light energy
ightarrow C_{6}H_{12}O_{6}+6O_{2}$. It uses carbon - dioxide, water, and light to produce glucose and oxygen. The chemical equation for cellular respiration is $C_{6}H_{12}O_{6}+6O_{2}
ightarrow 6CO_{2}+6H_{2}O+energy$. It uses glucose and oxygen to produce carbon - dioxide, water, and energy. The products of photosynthesis are the reactants of cellular respiration and vice - versa. (Assuming relevant content in Lesson 4 page X supports this, you need to check the actual lesson).
B. To determine if an organism is using photosynthesis, you can check for the presence of chlorophyll (as plants with chlorophyll can perform photosynthesis) and test for the uptake of carbon - dioxide and release of oxygen in the presence of light. To check for cellular respiration, you can test for the uptake of oxygen and release of carbon - dioxide in the dark or light (since cellular respiration occurs in most living cells constantly). (Assuming relevant content in Lesson 4 page Y supports this, you need to check the actual lesson).

Answer:

A. Photosynthesis and cellular respiration are complementary. Photosynthesis: $6CO_{2}+6H_{2}O + light energy
ightarrow C_{6}H_{12}O_{6}+6O_{2}$, cellular respiration: $C_{6}H_{12}O_{6}+6O_{2}
ightarrow 6CO_{2}+6H_{2}O+energy$. Their products and reactants are opposite. (Refer to Lesson 4 page [relevant page]).
B. For photosynthesis, check for chlorophyll, uptake of $CO_{2}$ and release of $O_{2}$ in light. For cellular respiration, check for uptake of $O_{2}$ and release of $CO_{2}$ in dark/light. (Refer to Lesson 4 page [relevant page]).
