Answer:
B. GLYCOLYSIS PROVIDES G3P AND F6P TO MAKE R5P
Explanation:
Ribose-5-phosphate is produced by the pentose phosphate pathway which is a process that works in line with glycolysis.
The need for NADPH and cell growth determines the production of ribose-6-phosphate in the cell.
Glucose-6- phosphate controls the flow of production from these two processes (pentose phosphate pathway and glycolysis)
During glycolysis, glycolytic intermediates can be used to produce R5P. This is so when the cells demands R5P than it desires NADPH
Glucose -6- Phosphate is converted to fructose-6-phosphate and glycealdehyde-3-phosphate during this process.
Two molecules of fructose-6-phosphate and a molecule of glyceraldehyde-3-phosphatr are then converted to three molecules of Ribose-5-phosphate by enzymes transketolase and transaldolase.
Answer:
Option B, He has a homozygous genotype
Explanation:
A dominant allele is one which will overshadow the expression of recessive allele. Thus, when a dominant allele and recessive allele appears together in the genotype of offspring , only the trait associated with the dominant allele is expressed. Therefore , if a recessive allele trait is to be expressed , the offspring must have both the recessive allele
Let us see case here
A. Allele for attached earlobes is recessive (e)
B. Allele for detached earlobes is dominant (E)
If offspring has EE genotype, then he/she would have detached earlobes
If offspring has Ee genotype, then also he/she would have detached earlobes as in heterogyzous genotype traits of dominant alleles are expressed.
If offspring has ee genotype, then only he/she would have attached earlobes
Genotype ee is a homozygous recessive genotype
Answer:
melanin
Explanation:
melanocytes produce melanin - the pigment which is ultimately responsible for your tan. The pinkish melanin travels up through the epidermis and is absorbed by other skin cells.
B. The lysosome membrane helps to keep its internal compartment acidic and separates the digestive enzymes from the rest of the cell.
