Answer:
C. oxidative deamination requiring NAD⁺.
Explanation:
Oxidative deamination is the first step in breaking down the amino acids in order to be converted into sugars. This process begins by removal of amino group of the amino acids. The amino group then becomes ammonium as it is lost and subsequently, undergoes the urea cycle to become urea in the liver. From there, It is released into the blood stream, where it is transferred to the kidneys, which will secrete the urea as urine.
The remaining portion of the amino acid becomes oxidized, forming an alpha-keto acid. The alpha-keto acid thus proceed into the Citric acid cycle, in order to produce energy.
The alpha-keto acid can also enter glycolysis, where it will be eventually converted into pyruvate. The pyruvate is then converted into acetyl-CoA so that it can enter the Citric acid cycle cycle and convert the original pyruvate molecules into ATP, or usable energy for the organism.
Answer: C
Explanation: Because the larger animals might starve if they don’t any smaller fishes to feed on unless they also leave the area or change there diet.
The worm would be unable to burrow and dig through the soil.
Chaetae are involved in the locomotion of the worm by giving the worm grip and <span>tools</span> to burrow <span>through</span>
the soil. <span> </span>Chaetae <span>are</span> made of chitin project from the body wall <span>on</span> each segment are arranged in 4 pairs and are
sited on the ventral surface - two pairs of ventral chaetae are found just
either side of the midventral line and two pairs are further out in the
ventrolateral position (that is just ventral of the side of the worm).
Answer:
Rough endoplasmic reticulum looks "rough" under a microscope because it has ribosomes attached to its surface.
Explanation:
Rough endoplasmic reticulum (RER) is a membrane organelle found in the cytoplasm of eukaryotic cells, which has ribosomes attached to its outer surface. Hence the name, rough endoplasmic reticulum. It has an important role in the synthesis of proteins. In ribosomes, the proteins are synthesized. The smooth endoplasmic reticulum (SER) does not contain ribosomes. It has an impotant role in the synthesis and storage of lipids. The proteins that are synthesized in the ribosomes are packaged into vesicles and transported to the Golgi apparatus by the rough endoplasmic reticulum. The Golgi apparatus which is located near the RER, modifies, transports and packages proteins for delivery to targeted destinations.
C because it has to have lots of radiation
