Humans cannot digest cellulose whereas cows can do so because

  1. Their gut contains certain bacteria capable of digesting cellulose.

  2. They have a many-chambered stomach.

  3. They have efficient grinding molars.

  4. They produce an enzyme cellulase which can digest cellulose.

A Correct answer
Explanation

Humans lack the enzyme necessary to digest cellulose. Hay and grasses are particularly abundant in cellulose, and both are indigestible by humans (although humans can digest starch). Animals such as termites and herbivores such as cows, koalas and horses all digest cellulose, but even these animals do not themselves have an enzyme that digests this material. Instead, these animals harbour microbes that can digest cellulose. Animals such as cows have anaerobic bacteria in their digestive tracts which digest cellulose. Cows are ruminants. Ruminants have several stomachs that break down plant materials with the help of enzymes and bacteria. The partially digested material is then regurgitated into the mouth, which is then chewed to break the material down even further. The bacterial digestion of cellulose by bacteria in the stomachs of ruminants is anaerobic, meaning that the process does not use oxygen.

B Correct answer
Explanation

The digestive system of Humans has many enzymes, and acids to break down and digest all kinds of different foods (carbohydrates. proteins and fats), but do not have the enzymes needed to break down cellulose. Cows, Goats, Sheep and other animals that graze on many organic foods(For example, grass) do have the enzymes needed to break down cellulose. Hence The part of food that is not digested in the body is Cellulose because the cellulose-digesting enzyme is absent.

So, the correct answer is 'cellulose'.

Triglyceride metabolism to convert fats into carbohydrates is helped by glyoxylate cycle. The organelle responsible for this is found in

  1. Rice seeds

  2. Caster seeds

  3. Wheat seeds

  4. More than one option is correct
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The glyoxalate cycle converts the fats into carbohydrates. This takes place in the organelles which are known as peroxisomes.

the lipids that are present in the cell are used to make energy.
This is found in many plants. This cycle is essential for seed germination.
So, the correct option is 'More than one option is correct'
