Question

The bioaccumulation of heavy metals in fishes can be evaluated by measuring the levels of ___.

• A. vitamins and lipids
• B. lipids and carbohydrates
• C. glycogen and lipids
• D. carbohydrates and vitamins

Answer 1

The correct option is C glycogen and lipids

$\bullet$ Fishes are quick to respond in a stressful environment (like polluted water) and the stress causes biochemical alterations in the body.
$\bullet$ The biochemical components like proteins, lipids, and glycogen form a reserve in the body.
$\bullet$ In a stressful environment, more energy is required for performing a metabolic process and these reserves are utilized as a source of energy.
$\bullet$ When the stress is strong, lipids and proteins are broken down and consumed as a source of energy, while the stress is low glycogen is consumed.
$\bullet$ The number of lipids, proteins, and glycogens consumed reveals the level of bioaccumulation.
