Question
- what type of energy goes into photosynthesis?
- what type of energy comes out of cellular respiration?
- write the equation for photosynthesis.
carbon dioxide + water → glucose + oxygen
- write the equation for cellular respiration.
glucose + oxygen → +
- explain why the text says that photosynthesis and cellular respiration are a cycle.
Question 3
Photosynthesis is a process in plants (and some other organisms) where light energy is captured and converted. The energy input for photosynthesis is light energy (specifically from the sun, solar energy).
Cellular respiration is the process where cells break down glucose to release energy. The energy that comes out is chemical energy in the form of ATP (adenosine triphosphate), which is used by cells for various functions.
The balanced chemical equation for photosynthesis, using the given reactants and products, and including the energy source (light) and the catalyst (chlorophyll, though sometimes not written in the basic equation) is: Carbon dioxide and water, in the presence of light energy and chlorophyll, react to form glucose and oxygen. In chemical formula terms: \( 6CO_2 + 6H_2O \xrightarrow[\text{Chlorophyll}]{\text{Light Energy}} C_6H_{12}O_6 + 6O_2 \)
