How many CO2 molecules are produced when three glucose molecules undergo cellular respiration? Explan ​

Biology
1 answer:
Svetlanka [38]3 years ago
7 0

Answer:

<u>18 molecules of </u>CO_{2}<u />

Explanation:

In heterotrophic nutrition, organisms ingest or absorb food made by autotrophs to obtain energy. Planta and other photosynthesizing organisms make sugars via photosynthesis, in a form of (partly) light-dependent biosynthesis.

In mitochondria, they break down sugars through aerobic respiration. For the sugar glucose, this results in the production of carbon dioxide and water along with energy in the form of ATP or adenosine triphosphate.  

C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP

glucose+ oxygen →  carbon dioxide+ water+ energy

For 3 molecules of glucose, multiply the number of reactants and products...

(C6H12O6+ 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP ) x 3

Thus...

3 C6H12O6+ 18 O2 → 18 CO2 + 18 H2O + ≅114 ATP

spayn [35]

Answer:

Endosymbiont theory was proposed by Lynn Margulis in 1967 which suggested the origin of Chloroplast and mitochondria in eukaryotic cells.

The theory suggested that chloroplast and mitochondria organelle originated by engulfing the cyanobacteria and proteobacteria by other prokaryotic bacteria.

This shows that Prokaryotes exhibit the following characters:

1. These were the first organisms on Earth

2. Lack membrane-bounded

3. Aerobic bacteria are these types of cells

Eukaryotes exhibit:

1. Have mitochondria

2. Includes organisms that carry out aerobic respiration

3. Can be a multicellular organism

4. Includes organisms that are photosynthetic

5. Might have chloroplasts
