Answer:

False

Explanation:

Vitamin K is essential for the body. It helps in blood clotting, contributes to bone health and can be used in premature babies. However, it is not essential for the absorption of vitamin B12 from the intestine, this is the role of cyanocobalamin rather than vitamin K.

Vitamin K is essential for the body. It helps in blood clotting, contributes to bone health and can be used in premature babies. However, it is not essential for the absorption of vitamin B12 from the intestine. In the human body, the absorption of Vitamin B12 already starts in the mouth by saliva and continues until the end of the small intestine. In this process, several proteins are required for B12 uptake. Initially, R proteins secreted in saliva and gastric juice unite with it and accompany it to the duodenum, where pancreatic juice proteases break their bonds and allow their absorption.

arsen [322]
I think you're talking about histones. Histones are proteins found in eukayotic cell nuclei. Histones are what DNA wrap around so it fits inside the nucleus and helps with the formation of chromosomes.

In the skeletal muscle cells of vertebrates, as many as ____________ molecules of atp are produced from one molecule of glucose.
shusha [124]
<span>In the skeletal muscle cells of vertebrates, as many as 38 molecules of ATP are produced from one molecule of glucose. This is less than might be expected, because electrons from NADH produced during glycolysis must be shuttled through the inner mitochondrial membrane at a cost.
</span>The energy of the electrons can be used to make ATP and in eukaryotes, glycolysis occurs in the <span>cytosol, outside mitochondria. </span>
