Answer:
The correct answer is given below:
Explanation:
Depending upon the availability of oxygen, pyruvic acid follows, a variety of metabolic pathways.
In the absence of oxygen or under anaerobic conditions, the pyruvic acid further metabolised into one of three pathways: lactic acid fermentation, alcohol fermentation and cellular anaerobic respiration. During fermentation or anaerobic respiration 2 ATP is produced.
In the presence of oxygen or under aerobic conditions, the pyruvic acid completely oxidised to carbon dioxide, water and 38 ATP.
Glassy igneous rocks (i.e. obsidian) are cooled very rapidly.
Spherical shaped bacteria are known as coccus bacteria.
Acid rain, or acid deposition, is a broad term that includes any form of precipitation with acidic components, such as sulfuric or nitric acid that fall to the ground from the atmosphere in wet or dry forms. This can include rain, snow, fog, hail or even dust that is acidic.
Answer:
