1 answer:

8 0

In animal and plant cells genetic information if contained within a nucleus, in bacterial cells there is no nucleus and so the genetic information is found within the cytoplasm of the cell but is not 'contained' in a more specific area. A small amount of DNA in the bacterial cell may be contained in an area of the bacteria called a plasmid, however not all bacterial cells have a plasmid.

Beriberi is caused by a deficiency of thiamine in the diet.

denis23 [38]

Answer:

Thiamine pyrophosphate (derived from vitamin B1) is a coenzyme required for the activity of pyruvate dehydrogenase enzyme complex.

Explanation:

Pyruvate is the end product of glycolysis. During aerobic cellular respiration, pyruvate is oxidatively decarboxylated into acetyl CoA which in turn enters the Kreb's cycle. Oxidative decarboxylation of pyruvate is carried out by enzyme complex pyruvate dehydrogenase (PDH). The first step is simple decarboxylation and is catalyzed by pyruvate decarboxylase of the PDH complex.

The enzyme pyruvate decarboxylase and has a tightly bound coenzyme, thiamine pyrophosphate. Thiamine pyrophosphate is derived from vitamin B1. Lack of vitamin B1 in the human diet leads to beriberi that is characterized by an increased concentration of pyruvate in blood urine since oxidative decarboxylation cannot occur due to lack of the coenzyme thiamine pyrophosphate.

What stores and delivers nutrients throughout the cell and transports waste to the cell membrane

mixer [17]

$\huge \sf \star{Answer} \star$

Vacuoles store water, food, and waste. The endoplasmic reticulum (ER) is a series of tunnels throughout the cytoplasm. They transport proteins from one part of the cell to another. Ribosomes are the protein factories of the cell.
