Coating of mucus( gastric mucosal barrier) protects the stomach from its acid
sun rays will not penetrate the ozone layer. they enters the earths atmosphere by the radiation processes. Ozone Layer gets depleted by the action of chlorofluorocarbons which were released by automobiles and refrigerators. and that results in the entry of UV rays which are harmful for life forms. and global warming phenomena is a result of greenhouse effect which explains the phenomenon of the heat which entered Earth's atmosphere by radiation, does not completely reflected back! rather, it (heat) gets stored in the atmosphere which results in the increase in temperature of the earth! and global warming was useful upto some extent in our ancient days. It resulted in the melting of himalayan ice mountains which in turn resulted in the increase of sea level. but now, global warming has become a major headache for us!
Every glucose molecule contains six atoms of carbon. One of those is grouped with one atom each of oxygen and hydrogen to form an aldehyde group, making glucose an aldohexose.
A new antibiotic is produced that inhibits the synthesis of acetyl-CoA and the electron transport chain in bacteria that normally require oxygen. For each glucose molecule that is metabolized, how many fewer ATP molecules will be produced?
38
4
36
34
2
Answer:
36
Explanation:
Glycolysis of cellular respiration produces only two molecules of ATP per glucose molecule. Kreb's cycle also forms 2 ATP molecules per glucose by substrate-level phosphorylation. However, oxidation of NADH and FADH2 by electron transport chain produces as many as 34 ATP molecules (almost 3 ATP per NADH and 2 ATP per FADH2). This obtains a total of 38 ATP molecules per glucose by the complete pathway of aerobic cellular respiration.
In presence of an antibiotic that inhibits Kreb's cycle and ETC of cellular respiration, a cell would produce only 2 ATP molecules (by glycolysis) per glucose. Therefore, it would obtain 38-2= 36 lesser ATP molecules.
