What is the connection between photosynthesis and cellular respiration?

Question

Isabella Anderson · Accepted Answer

Photosynthesis and cellular respiration are connected through #"CO"_2# and #"H"_2"O"# as these are the substrate in photosynthesis and end products in cellular respiration.

Photosynthesis and respiration are connected to each other through #"CO"_2# and #"H"_2"O"# which are end products in photosynthesis and substrate in respiration.

Both the processes involve production of #"ATP"# molecules.

However, production of #"ATP"# molecules occurs due to photo-phosphorylation in photosynthesis and oxidative phosphorylation in cellular respiration.

Photosynthesis is anabolic process as glucose molecule is formed from #"CO"_2# and #"H"_2"O"#, whereas cellular respiration is catabolic process in which glucose is broken down into #"CO"_2# and #"H"_2"O"#

Photosynthesis is endothermic process and cellular respiration is exothermic process.

#"ATPs"# produced in photosynthesis during photo-phosphorylation by entrapping solar energy are used in the synthesis of glucose.

The energy stored in #"ATP"# molecules is changed into chemical energy stored in glucose molecule.

The chemical energy stored in glucose molecule during its synthesis in photosynthesis is converted into ATP molecules during oxidation of glucose into #"CO"_2# and #"H"_2"O"# (oxidative phosphorylation).

undefined The two processes that occur in living things are photosynthesis and cellular respiration. In photosynthesis, plants use light, carbon dioxide, and water to produce glucose and oxygen. In cellular respiration, organisms break down glucose and oxygen to produce energy, carbon dioxide, and water. Both processes are complementary to one another because the carbon dioxide produced during cellular respiration is used in photosynthesis and the oxygen produced during photosynthesis is used in cellular respiration.
