Question

what is the chemical equation for photosynthesis?
a. \\(\ce{c6h12o6 + 6 o2 -> 6 co2 + 6 h2o + atp}\\)

b. \\(\ce{4 ch2nh2 + 13 o2 -> 4 co2 + 10 h2o + 4 no2}\\)

c. \\(\ce{ch4 + o2 -> co2 + h2o}\\)

d. \\(\ce{6 co2 + 6 h2o -> c6h12o6 + 6 o2}\\)

Explanation:

Photosynthesis is the process by which plants use carbon dioxide (\(CO_2\)) and water (\(H_2O\)) in the presence of light energy to produce glucose (\(C_6H_{12}O_6\)) and oxygen (\(O_2\)). Let's analyze each option:

• Option A: This is the equation for cellular respiration (breaking down glucose to release energy), not photosynthesis.
• Option B: This equation involves compounds with nitrogen (\(CH_2NH_2\)) and produces \(NO_2\), which is not related to photosynthesis.
• Option C: This is the combustion of methane (\(CH_4\)), not photosynthesis.
• Option D: This equation shows carbon dioxide and water reacting to form glucose and oxygen, which matches the process of photosynthesis.

Answer:

D. \(6 CO_2 + 6 H_2O
ightarrow C_6H_{12}O_6 + 6 O_2\)
