A compound is a molecule made of atoms from different elements. All compounds are molecules, but not all molecules are compounds. Hydrogen gas (H2) is a molecule, but not a compound because it is made of only one element. ... Atoms that share electrons in a chemical bond have covalent bonds.
Oxygen and glucose are the products of photosynthesis. Oxygen is used by plant for respiration or it gets dissipated in the air. Glucose is stored for feeding the plant. It is also stored in the form of starch
As verbalized, the enzyme glucose-6-phosphate dehydrogenase avails red blood cells function felicitously. Ergo, G6PD deficiency can cause hemolytic anemia characterized by having low calibers of red blood cells. The parasite that causes malaria does not survive well in G6PD deficient cells since they appear to have resistance against the disease.
The answer, I believe, is all of the above.
Hope this helps!!
