Explanation:
We know for sure that PK2 activates PK1 in a significantly signaling pathway. This is mainly because PK1 is permanently activated as a independent response which is observed in the status of PK2, by indicating that PK2 is fully activated downstream of PK1.
In the case that based on observation and experience, a setup were modified in a such a way PK1 was mutationally inactive and PK2 carried an activating mutation, we would not find any response observed since PK2 would not be able to activate PK1. The most importantly is that the logic is whether you discuss that PK1 activated PK2, I responded to this question part mainly based on this sequence.
Answer:
A
Explanation:
Carbohydrates is your body's main source of energy. They help to fuel your brain, your kidneys, your heart muscles, and your central nervous system.
1. During DNA elongation, polymerase enzyme adds new, free nucleotides to the three prime end of the newly forming strand, elongating it in five prime to three prime direction while the telomerase protects the important genes at the end of the chromosome from been deleted as the DNA strand shorten during DNA elongation.
2. During DNA elongation, helicase enzyme separates the double stranded DNA into single strand by melting the hydrogen bond that holds the DNA molecule together thus enabling each strand to be copied while the telomerase acts by preventing the telomere from been deleted during elongation.
Salivary amylase will be active for only an hour or so because the optimum pH for activity of amylase is about 6.7–7.0 which is available in the mouth but the pH of the stomach is acidic around 1-2 due to which the amylase enzyme becomes inactive in short-time.
The lingual lipase enzyme is present in the saliva but isn't active until reaching the stomach because this enzyme is acid stable and works efficiently in the stomach, not in the mouth.
Amylase enzyme is secreted in the mouth and is responsible for the breakdown of starch in food into sugars and it starts acting as soon as we put food in the mouth whereas Lingual lipase enzyme is secreted along with saliva but it is not active in the mouth rather its activity starts in the stomach which is responsible for the degradation of triacylglycerol molecules.

Using a slow- and fast-growing variant of bamboo, Wei and colleagues looked at cell division, growth, and gene expression (through transcriptomics, which measures all the genes being expressed by an individual) to discover which genes may be responsible for fast growth in bamboo. They found that the slow-growing variant had reduced expression of genes relating to cell wall construction, the plant hormone auxin (important for cell growth and cell division), and had irregular cell growth and cell walls. Wei and colleagues suggest that a reduced ability to produce and perceive auxin, combined with a weakened cell wall, are responsible for the slow growth seen in the bamboo variant.
