Is it true that some of the glucose required for cellular respiration in humans is obtained by eating glucose?

Answer 1

Human cells obtain energy by a process called respiration. This process is carried out in organelles in the cell called the Mitochondria. A Mitochondrion uses Glucose and Oxygen this reaction to form its two waste products, carbon dioxide and water, with the useful by product of energy, in the form of something called 'ATP'. Unless you are above the age of sixteenish, you will not need to know what ATP is, or even that it exists.

The word equation for respiration is:

Glucose + Oxygen → Carbon Dioxide + Water (+ Energy)

The last part in brackets is sometimes excluded.

The symbol equation is:

C6H12O6 + 6 O2 → 6 CO2 + 6 H2O

Due to the fact that energy has no chemical value, it is excluded from this equation universally.

This explanation is rather long, and I wrote it for intention of the asker reading it and taking interest. Of course, in the unfortunate circumstance in which you could not care less about all the time I have taken to answer this question in detail for you, the simple and boring one sentence answer is:

Human cells obtain energy via the process of Respiration (which takes place in the Mitochondria of the Cells). Depending on your year/grade, you may want to exclude/include the last part.

Good Luck!

Answer 2

Well, where do cells gets its nutrients?

We eat food and food is where our body gets its nutrients and energy.

There are four macromolecules that are very essential for our body: carbohydrates, lipids, nucleic acids, and proteins.

Glucose can be get from carbohydrates because carbohydrates monomers are monosaccharides. Monosaccharides are a unit of sugar.

In short, the answer to your question is yes.

Answer 3

Some glucose required for cellular respiration in animals may be obtained from cellulose.

Answer 4

Food digested contains glucose. When broken down the glucose is transferred in the blood to cells for respiration.

Answer 5

It is required for cellular respiration to take place. it is combined with oxygen to produce usable energy, carbon dioxide, and water

Answer 6
