Answer:

The correct answer is C in presence of oxygen production of acetyl CoA,TCA cycle and electron transport chain occur in a proper order.Whether in absence of oxygen lactic acid fermentation or alcoholic fermentation occurs.

Explanation:

Aerobic respiration occur in presence of oxygen which involves glycolysis,TCA cycle and electron transport chain.Aerobic respiration result in the catabolism of glucose to generate CO2,H2O and ATP.

     But in absence of oxygen or during anaerobic condition pyruvic acid is converted to either lactic acid by pyruvate dehydrogenase or to ethanol through alcoholic fermentation.

Mafia gain the interest and scrutiny of the public through their unique and fearful actions.

The process of Beta-oxidation and fatty acid synthesis are regulated in such a manner that neither process is active at the same
Neporo4naja [7]

Answer:

c) Acetyl COA carboxylase; citrate

Explanation:

Citrate serves as an allosteric activator for fatty acid synthesis and diverts the cellular metabolism from the consumption of metabolic fuel to the storage of fuel as fatty acids. When the concentrations of mitochondrial acetyl-CoA and ATP increase, citrate is transported out of mitochondria into the cytosol. In the cytosol, citrate serves as the precursor of cytosolic acetyl-CoA and an allosteric activator of acetyl-CoA carboxylase.

The enzyme Acetyl-CoA carboxylase has three functional regions. Its biotin carboxylase activates CO2 and its transcarboxylase transfers activated CO2 from biotin to acetyl-CoA to produce malonyl-CoA.

How is polar molecule different from a non polar molecule
m_a_m_a [10]

Polar molecules occur when two atoms do not share electrons equally in a covalent bond. While polar molecules have two parts with opposite charges (i.e., positive and negative), nonpolar molecules have no dipole, meaning that there is molecular symmetry, which results in no opposing charges.
