a) Pyruvate is a three-carbon molecule, so two molecules can be produced from each molecule of glucose. In total, from 4 molecules of glucose that enter glycolysis, there will be produced eight molecules of pyruvate.
b) PA becomes Lactic Acid instead of Acetyl CoA in anaerobic respiration (that is in auscense of oxygen), particularly when the cell carries out lactic acid fermentation, which is what can happen in the mitochondria of muscle cells when faced with a very demanding stimulus.
Answer:
the male part of a flower is called the stamen, it consists of a long slender stalk, the filament, with a two-lobed anther at the tip.
the female part of a flower is called the pistil, it consists of the stigma, the style, the overy and the ovule.
The answer is (B) Brain. This is because the brain is a part of what is known as the nervous system just as the lungs are part of what is known as the respiratory system.
Normally when the nerve impulse reaches the axon tip then it is ready to pass on to the next structure, therefore if the tips of the interneurons axon were damaged then it means the process of transmission from the axon to the next structure will not take place. Interneurons relays signals between the sensory neurons and the motor neurons, therefore with damaged tips the relay of information between the sensory neurons and motor neurons will not take place.
