Help please!........................................................
bogdanovich [222]

Answer:

The correct order would be

  • Glucose
  • ATP→ADP
  • H₂O
  • Pyruvate
  • CO₂

Explanation:

Following reactions occur in Glycolysis and Kreb's Cycle

  1. Phosphorylation of Glucose- In the first step of glycolysis, Glucose is converted into Glucose-6-Phosphate using 1 ATP molecule by Hexokinase enzyme. One phosphate group from ATP is attached to glucose by the enzyme, thus forming ADP.
  2. Dehydration- In the ninth step of Glycolysis, each of two molecules of  2-Phosphoglycerate are converted to Phosphoenol Pyruvate, by Enolase enzyme, releasing two H₂O molecules.
  3. Formation of Pyruvate- In the last or tenth step of Glycolysis, each of two molecules of Phosphoenol Pyruvate are converted to Pyrutave using an ATP by the enzyme Pyruvate Kinase.
  4. Oxidation Of Pyruvate to Acetyl-CoA- Before the Kreb's Cycle starts, the Pyruvate molecule obtained from the Glycolysis undergoes oxidative decarboxylation producing Acetyl-CoA and release of CO₂ and NADH.

explain why a father with blood group AB cannot donate for a child with blood group O when he marries a woman with blood group O
denis-greek [22]

The odds are astronomical for a father with AB(IV) to have an O(I) child. The only possible way for this phenomenon to occur is if there was a nondisjunction in the ovogenesis for the 9th chromosome and the father also had a nondisjunction for the same chromosome(A sperm cell with no 9th chromosome fertilized an ovum with two 9 chromosomes).

A person with AB cannot donate to a person with O because the receiver has antibodies(alpha and beta) that bind to the antigens on the AB blood cells, causing death.

Cerebral Palsy is a brain injury it occurs while the brain is developing this could be before, during, or after birth. Mutation which is a sudden heritable change in the genome of an individual can result into cerebral palsy when the child is still developing. Mutation affects the gene changing it from it normal state to an abnormal one some mutation can be beneficial but for palsy it is detrimental one affecting the growth and development of the child.

severe jaundice in the infant could also lead to cerebral palsy in an infant child

This damage affects child’s muscle control, muscle coordination, muscle tone, reflex, posture and balance.

It can also impact a child’s fine motor skills, gross motor skills, and oral motor functioning
