Answer:
Pyruvate kinase is the important enzyme that catalyzes the conversion of phosphoenol pyruvate into the pyruvate in the glycolysis cycle. This step generates the ATP molecule.
The regulation of the pyruvate kinase is done by the allosteric regulation and fructose 1,6 biphosphate activates the pyruvate kinase. This regulation is important as it control the metabolites present in different organs. The metabolites like fructose, galactose enters in the glycolysis from the liver after the particlar step of glycolysis.
The correct answer is B. T, seconds.
Waves are the vibrations that originates from a fixed position in a oscillating motion. it causes disturbance to travel through a medium. Wave period is a time by a wave to complete one cycle. Time period is denoted by the symbol T. The unit used for this quantity is seconds.

Answer:
1. DNA polymerase
2. DNA primase
3. DNA helicase
Explanation:
DNA replication is the process whereby the genetic material gets duplicated i.e producing an identical copy of a sequence. This process requires the aid of certain enzymes that play specific functions. Some of the important enzymes include:
- DNA polymerase is the enzyme considered to be the most important because it directly adds nucleotides to the strand based on what it reads on the template strand.
- DNA helicase is the enzyme that separates the double stranded DNA molecule into two single strands that forms a structure called REPLICATION FORK.
- DNA primase is the enzyme that adds a short RNA sequence called PRIMERS to the lagging strand of DNA in order for DNA polymerase to start its nucleotide synthesis.
Water Vapor - (least dense)
Ice
Liquid Water - (most dense)
Explanation:
While you would expect that the density of a substance increases with lowered temperatures - because the particles get closer together hence there are more particles of the substance per unit volume at lower temperatures-, there is an exception in water. It is even called <u>water anomaly</u>.
Ice, which is the solid and most compact form of water, is less dense than water at <u>4° Centigrade</u>. This is why ice sheets float on oceans in the polar regions.
