What example is lactose and cellulose
What example is lactose and cellulose - 1


Answer 1


They can be divided into simple carbohydrates, which include monosaccharides (e.g., glucose, fructose, galactose) and disaccharides (e.g., sucrose, lactose), and complex carbohydrates, which comprise starch and nonstarch polysaccharides (e.g., starch, glycogen, cellulose)

Answer 2

Final answer:

Lactose and cellulose are carbohydrates performing different functions: lactose is a disaccharide that provides energy and cellulose is a polysaccharide that maintains plant structure and serves as dietary fiber in human diet.


Lactose and cellulose are both types of carbohydrates, but they serve different functions. Lactose, also known as 'milk sugar', is a disaccharide made up of glucose and galactose. It is found in milk and dairy products. Humans ingest lactose and break it down with the enzyme lactase, providing energy for the body. People with lactose intolerance lack this enzyme.

Cellulose, on the other hand, is a polysaccharide and the main component of plant cell walls. It helps plants maintain their structure. Humans and many other animals cannot directly digest cellulose because they lack the necessary enzymes. However, some animals like cows and termites can digest cellulose with the help of microorganisms in their digestive system. Cellulose is an important part of human diet as dietary fiber.

When faced with a sudden drop in environmental temperature, an endothermic animal will ________.experience a drop in its body temperature
wait to see if it goes lower
increase muscle activity to generate heat
add fur or fat to increase insulation


Answer: The correct answer would be increase muscle activity to generate heat.


Endothermic animals are those which maintain their body temperature mainly by their metabolic activity irrespective of environmental heat.

In case, there is a drop in environmental temperature then endothermic animals increase their metabolic activity and metabolize sugars and fats at a faster rate.

It release more heat and increase the body temperature.

One the various methods for increasing metabolism is increase in muscle activity such as done in shivering. Shivering increases muscle activities which increases body temperature.

Final answer:

An endothermic animal would increase muscular activity to generate heat in response to a sudden drop in environmental temperature. This internal heat production is part of their physiological adaptation to maintain stable body temperature in varying conditions.


When faced with a sudden drop in environmental temperature, an endothermic animal will typically increase muscle activity to generate heat. Unlike ectothermic animals, endotherms maintain a stable internal body temperature despite changes in the environment. They are capable of doing this because they generate their own heat internally, often through processes like muscular activity including shivering. Therefore, in an attempt to sustain a constant body temperature when exposed to a colder environment, muscular activity within the animal would increase to produce more heat. This, in turn, helps to counteract the cooling effect of the lower external temperatures.

Cells that secrete hormones into the bloodstream which are then carried away to target cells are referred to as __________ cells.a. paracrine
b. endocrine
c. autocrine
d. exocrine


b. endocrine

Paracrine cells are the ones that secrete a sign directly to its neighbors, to the extra cell space and not to the blood.

Endocrine cells are the ones that secrete a hormone to the blood system to be distributed to some specific place in the body.

The autocrine system is the release of a hormone from the cell to that same cell.

The exocrine glands are those who release a specific type of hormone or enzyme to some part of the body, through canals.

When an enzymatic reaction is in progress, do you expect to see an increase, decrease or no change in each of following: (i) substrate (ii) product (iii) enzyme


During an enzymatic reaction, their is an decrease in the concentration of substrate, an increase in the concentration of product, and no change in the concentration of the enzyme.

What is enzymatic reaction?

A reaction, which is mediated with the help of an enzyme is termed as enzymatic reaction. A substance, which functions as a catalyst in living organisms and regulate the rate at which the chemical reactions takes place is known as an enzyme.

The enzymatic reactions follows the lock and key model, in which the free enzyme combines with the substrate and forms the enzyme-substrate complex, this is further catalyzed into the enzyme-product complex, from which the free enzyme and product get discharged. The product never further binds with the free enzyme.

In the reaction, the substrate get used up thus its concentration decreases, while the formation of product takes place thus its concentration increases. However, there is no change in the concentration of the enzyme as it does not get used up in the process.

Thus, in enzymatic reaction, substrate decreases, product increases, and enzyme concentration remains the same.
