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

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 : haversian

[explanation: -(compact bone is organized as parallel columns, known as haversian systems, which run lengthwise down the axis of long bones. these columns are composed of lamellae, concentric rings of bone, surrounding a central channel, or haversian canal, that contains the nerves, blood vessels, and lymphatic system of the bone)]
