The complementary strand of RNA to the following DNA strand AAA GCT TTG GAC CTA will be UUU CGA AAC CUG GAU.
To determine the complementary strand of RNA to the given DNA strand, we need to first convert the DNA sequence into RNA by replacing the nucleotide thymine (T) with uracil (U).
Thus, the RNA sequence would be UUU CGA AAC CUG GAU.
It is important to note that RNA is single-stranded, meaning it only has one complementary strand, unlike DNA which has two complementary strands.
In RNA, the complementary strand is formed through base pairing between the nitrogenous bases, with adenine (A) pairing with uracil (U) and guanine (G) pairing with cytosine (C).
Therefore, the complementary strand of RNA to the given DNA strand would be formed by replacing each nucleotide in the DNA strand with its complementary base in RNA, resulting in the sequence: UUU CGA AAC CUG GAU.

co-factors are highly important to enzymatic reactions but are likely restored by the enzyme by the conclusion of the reaction
Co-factors are molecules that are required for enzymes to function properly. Enzymes are biological molecules that catalyze chemical reactions in living organisms, and they work by binding to a specific substrate and then converting it into a product.
Co-factors are often small molecules, such as vitamins, minerals, or other organic compounds, that are required for the enzyme to bind to the substrate and to catalyze the reaction. Co-factors are important because they help to activate the enzyme and make the reaction more efficient. Without the co-factor, the enzyme would not be able to bind to the substrate and the reaction would not occur. Co-factors are also often required in small quantities, and their presence is often limited by the availability of the substrate.
After the enzyme reaction is completed, the co-factor is typically not restored by the enzyme. Instead, the co-factor is usually degraded or removed from the reaction. This is because the co-factor is not needed for the enzyme to continue to function, and its presence could interfere with the next reaction.

why is the glucagon not able to compensate for decreasing blood sugar levels
Glucagon is not able to compensate for decreasing blood sugar levels due to various factors, including insulin resistance, impaired glucagon secretion, and dysfunction in the liver's response to glucagon.
Glucagon is a hormone produced by the pancreas that plays a crucial role in regulating blood sugar levels. It acts opposite to insulin, promoting the release of glucose from glycogen stores in the liver, thereby increasing blood sugar levels. However, in certain conditions, glucagon may not be able to compensate for decreasing blood sugar levels.
One factor contributing to this is insulin resistance, a condition commonly associated with type 2 diabetes. In insulin resistance, the body's cells become less responsive to the effects of insulin, leading to impaired glucose uptake. This can make it challenging for glucagon to counteract decreasing blood sugar levels because the cells are not effectively utilizing the glucose released by the hormone.
Another factor is impaired glucagon secretion. In some cases, the pancreas may not produce adequate amounts of glucagon or may release it inappropriately. This can disrupt the normal balance between insulin and glucagon and hinder the ability of glucagon to raise blood sugar levels.
Additionally, dysfunction in the liver's response to glucagon can limit its compensatory action. The liver is responsible for releasing glucose into the bloodstream when stimulated by glucagon. However, liver dysfunction, such as fatty liver disease or liver damage, can impair its ability to respond appropriately to glucagon, resulting in inadequate glucose release and ineffective compensation for decreasing blood sugar levels.
