Answer:

Penguins in general are distributed close to each other to be able to withstand the extreme cold, characteristic of the ecosystems they inhabit. They also group together to incubate their eggs.

They perform a series of coordinated movements that help them fight low temperatures, being careful to drop the egg.

What amino acid can be obtained by the reductive amination of γ-ketoglutaric acid
Svetradugi [14.3K]

Answer:

Glutamic acid

Explanation:

Reductive amination is a form of amination that involves the conversion of a carbonyl group to an amine via an intermediate imine. The carbonyl group is most commonly a ketone or an aldehyde. In this reaction, in the presence of enzyme glutamate dehydrogenase, ammonium ion directly combines with alpha-ketoglutaric acid, to form glutamic acid (amino acid) and for this to happen, a reduced coenzyme (NADPH) is required.

The biosynthesis of glutamic acid  can be obtianed from the reductive amination of γ-ketoglutaric acid

γ-Ketoglutaric acid is a common precursor in synthesis of glutamic acid. Addition of NADPH and ammonia or alpha amino acid with   γ-Ketoglutaric acid produces glutamic acid. Enzymes involved in this reduction amination  process are glutamate dehydrogenase and/or transaminase.

Mashutka [201]

The new hypotheses proposed by different scientists are often criticized by the others because these new hypotheses contradict the ideas and hypotheses that already exist. Adapting one's mind to a new hypotheses explaining a past event is often difficult when more clear hypotheses were already given earlier. Thus, the hypotheses suggesting the extinction of the dinosaurs are difficult for the scientific community to accept.
