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.

In some bunnies, the gene for fur color is controlled by condominance. The allele for gray color is G and the allele white color
Inessa05 [86]

Answer:

Genotype gray bunnies: GG

Genotype white bunnies: WW

Genotype gray and white bunnies: GW

Explanation:

In diploid species (2n), organisms receive one gene copy (allele) from each parent. Codominance is a relationship that occurs when both alleles of the same gene show dominance. In consequence, the expression of both alleles in heterozygous individuals results in a new phenotype. In this example, the expression of G and W alleles results in a gray and white phenotype. Examples of codominance include individuals with type AB blood group in humans or the roan coat color in horses.
