Carbohydrates and Biomolecules Questions

Multiple choice general knowledge science & technology
  1. Lactose

  2. Sucrose

  3. Fructose

  4. Glucose

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Lactose is a disaccharide sugar composed of glucose and galactose that is naturally present in milk from mammals. It is the primary carbohydrate in dairy products. Sucrose is table sugar, fructose is fruit sugar, and glucose is a simple sugar found in many foods but not primarily in milk.

A Correct answer
Explanation

The new Perk chocolate variant formulation highlighted glucose as the sugar type used, differentiating it from regular chocolate bars that primarily use sucrose.

B Correct answer
Explanation

Maltose is produced when starch breaks down during the germination of barley (malting), which is then fermented by yeast to produce alcohol in beer brewing. While maltose also appears in bread making through starch breakdown, it's most directly and prominently associated with beer production.

D Correct answer
Explanation

Unlike the liver and muscles which store significant glucose as glycogen, brain tissue (neurons) cannot store glucose. The brain depends entirely on continuous blood glucose delivery, though astrocytes can store very small amounts of glycogen.

C Correct answer
Explanation

Fruits primarily contain sucrose, which is a disaccharide composed of glucose and fructose. While fruits also contain free glucose and fructose in varying proportions depending on the fruit type, sucrose is the dominant sugar form in most fruits, unlike lactose found only in milk or maltose in germinating grains.

Multiple choice general knowledge science & technology
  1. Fructose

  2. Maltose

  3. Lactose

  4. Glucose

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Lactose is the natural sugar present in milk, making up about 4-5% of milk's composition. It is a disaccharide composed of glucose and galactose. Fructose is fruit sugar, maltose is found in germinating grains, and glucose is a simple sugar present in many foods but not specifically characteristic of milk.

Multiple choice general knowledge
  1. True

  2. False

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Despite their tart taste, lemons contain more natural sugar per pound than strawberries. Lemons contain about 2-3g sugar per fruit, but they have more sugar by weight compared to strawberries which are approximately 92% water and have only about 8g sugar per cup. The perceived sweetness comes from different sugar compositions and acidity levels.

Multiple choice general knowledge
  1. cellose

  2. Lactose

  3. Glucose

  4. none

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Rayon is a regenerated cellulose fiber made from cellulose (wood pulp or plant fibers). The term 'cellose' appears to be a typo/variant spelling of cellulose. Lactose and Glucose are sugars, not fiber materials.
