Final answer:
Yes true, biomolecules often have basic or acidic functional groups such as carboxyl and amino groups, which are integral to their function in living organisms.
Step-by-step explanation:
The statement that biomolecules often have basic or acidic functional groups is true. Functional groups such as hydroxyl, methyl, carbonyl, carboxyl, amino, phosphate, and sulfhydryl are commonly found in biomolecules. These groups significantly influence the chemical properties and behaviors of biomolecules. For example, a carboxyl group (COOH) can release a hydrogen ion (H+), forming a negatively charged carboxylate ion (COO-) and thus behaving as an acid. Alternatively, amino groups (-NH2) can accept H+ to form -NH3+, and this gives the functional group basic characteristics. These groups are pivotal in determining how biological molecules like DNA, proteins, carbohydrates, and lipids interact and function within living organisms.
