Answer - The chromosomes has to be crucially duplicated and it happens actively during the resting phase or interphase.

Reasoning - During the resting phase or interphase you call it, Is important to have the same exact DNA or Chromosomes to be duplicated. If the chromosomes did not duplicate during the interphase then the split of the cell would be unbalance and uneven and likely to cause defects.

The synaptic gap separates adjacent neurons.

<h3>What are neurons and what do neurons perform?</h3>

Neurons are the primary functional components of the nervous system, and they generate electrical signals called action potentials, which allow them to quickly convey information over large distances. Although glia primarily support the neurons, they are nonetheless crucial for the proper operation of the nervous system.

<h3>What makes neurons so important?</h3>

Information is transported throughout the human body by neurons. They assist in coordinating all of the vital operations of life by using electrical and chemical signals.

<h3>What three types of neurons are there?</h3>

However, we may say that there are three different types of neurons in the spinal cord, sensory, motor, and interneurons.

2. In gluconeogenesis, it takes two enzymes to convert pyruvate to phosphoenolpyruvate. a. Explain what is happening chemically
Marina CMI [18]

Answer:1. Pyruvate carboxylase

2. Phosphoenol pyruvate carboxy kinase

Explanation:

The conversion of pyruvate to phosphoenol pyruvate is catalyzed by two enzymes Pyruvate carboxylase and phosphoenol pyruvate carboxy kinase

1. Pyruvate carboxylase reaction

Pyruvate in the cytoplasm enters the mitochondria. Then, carboxylase of pyruvate to oxaloacetate is catalysed by a mitochondrial enzyme, pyruvate carboxylase. It needs the co-enzymes biotin and ATP.

The oxaloacetate formed has to be transported from the mitochondrial to the cytosol because further reaction of gluconeogenesis are taking place in cytosol.

2. Phoaphoenol pyruvate carboxy kinase (PEPCK)

In the cytoplasm, PEPCK enzyme then converts oxaloacetate to phoaphoenol pyruvate by removing a molecule of CO2. GTP or ITP donates the phosphate group.

The net effect of these two reactions is the conversion of pyruvate to phoaphoenol pyruvate. This circumverts the irreversible step in glycolysis catalyzed by pyruvate kinase (step 9 if glycolysis)
