Which category of carbon-based molecules includes sugars and starches?
A
carbohydrates
B
lipids
C
proteins
D
nucleic acids
Explanation: 

Detailed explanation-1: -Carbohydrates include sugars and starches.

Detailed explanation-2: -Carbohydrates are the most common class of biochemical compounds. They include sugars and starches. Carbohydrates are used to provide or store energy, among other uses.

Detailed explanation-3: -Starch, glycogen, cellulose, and chitin are examples of polysaccharides. Starch is the stored form of sugars in plants and is made up of amylose and amylopectin (both polymers of glucose).

Detailed explanation-4: -The white stuff we know as sugar is sucrose, a molecule composed of 12 atoms of carbon, 22 atoms of hydrogen, and 11 atoms of oxygen (C12H22O11). Like all compounds made from these three elements, sugar is a carbohydrate.

Detailed explanation-5: -Polysaccharides: Starch, Glycogen, and Cellulose However, sugar units can be bonded or linked together to form polysaccharides, which consist of many sugars linked together to form extensive chains of sugars. Plants store energy as starch, which consists of very long chains of glucose linked together.
