Detailed explanation-1: -(a) On homogenising any tissue in an acid, the acid soluble pool represents cytoplasm. Homogenisation is a process whereby a biological sample is brought to a state such that all fractions of the sample are equal in composition.

Detailed explanation-2: -Final answer: The acid-soluble pool represents roughly the cytoplasmic composition, calcium ions are unlikely to present in it.

Detailed explanation-3: -The acid soluble pool has those compounds which have molecular weights ranging from 18 to around 800 Dalton’s approximately. It has only four types of organic compounds i.e., proteins, nucleic acids, polysaccharides and lipids. Lecithin or phospholipid is present in a cell membrane.

Detailed explanation-4: -Rotor-Stator: The rotor-stator, or what is commonly known as the handheld homogenizer, was first commercialized for the laboratory in the 1950s. This homogenizer is one of the most widely used tools for homogenizing plant and animal tissues.

Detailed explanation-5: -In an acid soluble pool, the substances have a molecular weight of range of 18-800 Daltons. Acid-insoluble pool has molecules that are heavier substances (more molecular weight). Hence the substances in acid soluble pools are called micromolecules and in acid-insoluble pools are called macromolecules.
