Question

write down the equations for photosynthesis and cellular respiration. write a paragraph describing where these processes happen. talk about the reason for these processes, how the equations are connected and how matter and energy are conserved in both photosynthesis and respiration. review the glossary to prepare for your next assignment.

Explanation:

1. Equations:

• Photosynthesis: $6CO_2 + 6H_2O+light

ightarrow C_6H_{12}O_6 + 6O_2$. It occurs in chloroplasts of plant cells. The purpose is to convert light - energy into chemical energy in the form of glucose.

• Cellular respiration: $C_6H_{12}O_6+6O_2

ightarrow 6CO_2 + 6H_2O + energy$. It occurs in the mitochondria (aerobic respiration) and cytoplasm (anaerobic respiration) of cells. The purpose is to release energy stored in glucose for cellular activities.

1. Connection: The products of photosynthesis ($C_6H_{12}O_6$ and $O_2$) are the reactants for cellular respiration, and the products of cellular respiration ($CO_2$ and $H_2O$) are the reactants for photosynthesis.
2. Conservation of matter and energy: In photosynthesis, light energy is converted into chemical energy stored in glucose. In cellular respiration, the chemical energy in glucose is released. Matter is conserved as the number of atoms of each element is the same on both sides of each equation. Energy is conserved as it is just converted from one form to another.

Answer:

The equation for photosynthesis is $6CO_2 + 6H_2O+light
ightarrow C_6H_{12}O_6 + 6O_2$, occurring in chloroplasts. The equation for cellular respiration is $C_6H_{12}O_6+6O_2
ightarrow 6CO_2 + 6H_2O + energy$, occurring in mitochondria and cytoplasm. They are connected as products of one are reactants of the other. Matter and energy are conserved as atoms are balanced and energy is just converted between forms.
