Question

Sugars are not as good as fats as a source of energy for cellular respiration, because sugars.

• A. Produce toxic amino groups when broken down
• B. Contain more hydrogen
• C. Usually bypass glycolysis and the Krebs cycle
• D. Contain fewer hydrogen atoms and electrons

Answer 1

The correct option is A Produce toxic amino groups when broken down

Sugars, when broken down, produces toxic amino groups. During Cellular Respiration, sugar is broken down to CO${}_2$and H${}_2$O, and in the process, ATP is made that can then be used for cellular work. Carbohydrates, fats, and proteins can all be used as fuels in cellular respiration, but glucose is most. In glycolysis, the 6-carbon sugar, glucose, is broken down into two molecules.

So the correct answer is 'Produce toxic amino groups when broken down'.
