Question

What are the different ways in which glucose is oxidised to provide energy in various organisms​

Answer 1

Answer:

Aerobic respiration, Anaerobic respiration in yeast, Anaeorbic respiration in muscles.

Explanation:

1) Aerobic respiration: In this case pyruvate is broken down into water and carbon dioxide along with release of energy. It commonly occurs in mitochondria of cells.

2) Anaerobic respiration in yeast: In yeast cells during fermentation pyruvate is converted into ethanol and C02 in the absence of 02.

3) Anaeorbic respiration in muscles: Due to lack of oxygen, eg. during vigorous running or exercise, in human muscles, pyruvate is converted to lactic acid.

Answer 2

Carbohydrates, carbohydrates, carbohydrates or saccharides are biomolecules composed mainly of carbon, hydrogen and oxygen, although some of them also contain other bioelements such as nitrogen, sulfur and phosphorous. The main functions of carbohydrates in living beings are to provide immediate energy (not in vain they are the main source of energy, through an oxidation process, in most non-photosynthetic cells), as well as a structural function
