increases in insulin increase co2 production in liver and brain but not adipose tissue true or false?

The correct answer is false. Insulin speeds up glucose transport across cell membranes and promotes glycogen synthesis and slows down glycogen breakdown.

Adipokines, proinflammatory substances, and free fatty acids are released by adipose tissue, an endocrine organ that affects both glucose and lipid metabolism. These substances reduce muscle ATP synthesis and glucose metabolism, encourage the synthesis of harmful lipid metabolites, and change insulin signaling. Insulin affects adipose tissue in two ways: 1) by increasing glucose absorption and triglyceride synthesis, and 2) by reducing triglyceride hydrolysis and the release of FFA and glycerol into the bloodstream. Elevated plasma FFA levels have been demonstrated to impair muscle insulin signaling, promote hepatic gluconeogenesis, and impair glucose-stimulated insulin response. Adipose tissue insulin resistance, which is the impaired suppression of lipolysis in the presence of high insulin levels, has been linked to glucose intolerance.

Allushta [10]

Answer:

Transcription factor binding would be reduced or eliminated, and transcription of the gene would decrease dramatically.

Explanation:

Mutation means the changing of the structure of the gene that results in the variant form which may be transmitted to the subsequent generations.  They are caused by the altering the the single base units in the DNA of the species.

In both eukaryotic as well as prokaryotic, the mutation can affect the diversity in the future generation of the cells.

The eukaryotic mutation of the gene affects the transcription of the gene as the transcription factor binding will be lowered or will be eliminated and the transcription of this gene will decrease.

There are some similarities between prokaryotic and eukaryotic cells. What structures is found in both prokaryotic and eukaryoti
patriot [66]

Answer:

DNA, ribosomes, plasma membrane and cytoplasm are the structures that are found in both.

Explanation:

Prokaryotes are the organisms that do not have a nucleus and other membrane-bound organelles and eukaryotes have a membrane-bound nucleus and another membrane-bound organelle.  

Apart from this there are some similarities between prokaryotic and eukaryotic cell like both have a highly selective cell membrane, they both have cytoplasm, both have DNA and ribosomes which is responsible for the expression of genes. Therefore DNA, ribosomes, plasma membrane, and cytoplasm are the structures that are common in both prokaryotes and eukaryotes.

What are the two active sites or domains on a repressor protein?
n200080 [17]

Answer:

DNA binding domain and allosteric domain

Explanation:

Repressors are proteins that inhibit gene expression, They usually have DNA or RNA binding site which enables them to binde to the operator or associated silencers. Allosteric domain is the site for the binding of other molecules, such as  corepressors and inducers that regulate repressor's activity.

Identify the analogous structures
ra1l [238]

Answer: Here you go!

Explanation:

Analogous structures are structures that are similar in unrelated organisms. The structures are similar because they evolved to do the same job, not because they were inherited from a common ancestor. For example, the wings of bats and birds, shown in Figure below, look similar on the outside
