Answer:</h2>
Glucokinase or Hexokinase is a enzyme used at the first step of glycolysis.
<h2>
Explanation:</h2>
- Glucokinase is a Isoenzyme(enzymes which differs in the sequence of amino acids but catalyses the same reaction) of Hexokinase .
- Glucokinase (hexokinase D) is present only in liver and pancreas whereas hexokinase is present in all cells.
- In first step of glycolysis i.e formation of glucose-6-phosphate from glucose is completed with the help of hexokinase. In this step a ATP molecule is consumed i.e ATP is converted to ADP
Result: Glucokinase and hexokinase are used in the first step of glycolysis.
Answer/Explanation:
Pollution during the industrial revolution caused trees to become covered with soot, making them darker. This dark appearance meant that the peppered moth, which usually had a light colour, was clearly visible against the tree. This meant it was easier for predators to identify. As a result, their numbers decreased because they were an easier target.
However, there was also a rarer form of the moth, which was dark in colour. These were initially very rare. However, because of the change in the tree colour owing to the industrial revolution, these moths were better suited to the environment, as they were more camouflaged against the dark tree. This meant it was easier for them to avoid predators, and so they were more likely to survive to reproductive age and pass on the genes that produce the dark colour. This meant that the dark moths increased in number.
An organism or part having or consisting of many cells.
Our central nervous system is made up of two tissues: the gray matter and the white matter. The gray matter is composed of the dendrites and the axon terminals where synapses are. These synapses are the links between neurons that transmits electrochemical signals. The white matter, on the other hand, is composed of axons that connect all the gray matter together. Therefore, the answer is: <span>white matter is primarily in the CNS in the presence of myelinated axons</span>
