Answer:
(E) Phosphoglucose isomerase (phosphohexose isomerase or glucose-6-phosphate isomerase)
Explanation:
Glyocolysis is break down of glucose into pyruvate.
Isomerization:The second step of glycolysis involves the conversion of glucose-6-phosphate to fructose-6-phosphate (F6P). This reaction occurs with the help of the enzyme phosphoglucose isomerase (PI). As the name of the enzyme suggests, this reaction involves an isomerization reaction.
Yeast mutant lacking phopshoglucose isomerase unable to performed this step and that's why it unable to grow in media containing glucose while in fructose break down this step is not required so it is able to grow in media containing fructose.
Deletion of phosphoglucose isomerase, prevents growth on glucose; therefore, phosphoglucose isomerase mutant is able to grown in a fructose medium.
The answer to this question would be: True
Fraternal twins are made from 2 different eggs and fertilized by two different sperm. That makes them just like 2 siblings since the genetic in their egg and sperm is different, not same. This can happen if there is two egg released by the womb at the same time.
I am pretty sure it would be more difficult ok Jupiter
Answer:
When homologous chromosome pairs align on the spindle during metaphase I the orientation of one pair is independent of the orientation of any other pair. This is known as independent assortment. Humans have 46 chromosomes, arranged as 23 pairs.
Explanation:
The lungs work by expanding and going back to their original size when you inhale and exhale. The rib cage also expands so the lungs can have more air inside and expand. Due to deformities, the rib cage might not expand and/or the diaphragm might not lower itself, which might lead to pressuring the lungs not to expand and having a lower volume of air inside. This leads to breathing difficulties.
