Question

If 2000 calories are ingested, 42 calories lost through excretory energy and 300 calories available for tissue production, what are the metabolic costs?

Answer 1

Metabolic cost is the energy which is utilised by the cell for carrying out function.

Here ingested energy = 2000 calories

Excretory energy= 42 calories

Calories available = 300 calories

Metabolic cost = Ingested energy- ( Excretory energy+ calories available)

= 2000- (42+300}

= 2000- (342)

= 1658 calories.

The metabolic cost is 1658 calories.
