c. both

a. Photorespiration

Explanation:

Photorespiration is the metabolic process that results from Rubisco's lack of specificity (O 2 consumption and light-related CO 2 production)

Photorespiration occurs due to the double activity exerted by the enzyme ribulose-1,5-bisphosphate carboxylase / oxygenase (rubisco), which catalyzes two competing reactions: the addition of CO2 to ribulose-1,5-bisphosphate (RuBP), forming two molecules of 3-phosphoglycerate (PGA), which are used in the thermochemical step of photosynthesis and the addition of O2 to RuBP, producing a PGA and a phosphoglycolate molecule, characterizing photorespiration.

Thus, the rubisco, present in chloroplasts, besides exerting the carboxylase activity, which initiates the Calvin cycle, is equally capable of exerting oxygenase activity, having both RuBP as substrate in both cases.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
