Answer;
-COOH
Explanation;
The carboxyl group includes both a keto oxygen and a hydroxyl group; Carboxyl groups are weak acids, dissociating partially to release hydrogen ions. The carboxyl group (symbolized as COOH) has both a carbonyl and a hydroxyl group attached to the same carbon atom, resulting in new properties.
The carboxyl functional group is an acidic functional group frequently found in biological molecules. It is found in amino acids, proteins. fatty acids, acetic acids and other organic acids.
Answer:
The most appropriate answer would be C.electron carriers such as NADP⁺.
High energy electrons are transported through electron transport chain embedded in a thylakoid membrane in order to produce energy rich compounds such as ATP and NADPH.
It is also called as light dependent reaction of photosynthesis. It includes four major protein complexes: photosystem II, photosystem I, cytochrome b6f complex, and ATP synthase.
The electron first gets excited from chlorophyll a present in the reaction center (P₆₈₀ and P₇₀₀) of two photosystems (PS II and PS I) . The electron in PS II is replenished by photolysis of water.
Different electron carriers (such as plastoquinone, plastocyanin, pheophytin, chlorophyll A₀ etc) are present which help in transferring this high energy electron from one complex to another. NADP⁺ is the final acceptor of the electron and gets reduced to NADPH.
NADPH and ATP are then used in dark reaction in order to fix carbon into sugars.
The most widely effective solvent for organisms is a material that is nonpolar. This is because most of the molecules present in organisms are nonpolar so it would only dissolve in nonpolar solvents like lipids, DNA, proteins, amino acids and fats. Nonpolar molecules would share their electrons equally resulting to having no partial charges in the molecule. The electronegativities are cancelled by each atom. Examples of this are most of the organic compounds like benzene and hexane, carbon tetrachloride is also a nonpolar molecule. To identify whether the molecule is nonpolar or polar, you need to look at the structure and the electronegativities of the atoms.
