HEART RATE IS CONTROLLED BY THE TWO BRANCHES OF THE AUTONOMIC (INVOLUNTARY) NERVOUS SYSTEM.THE SYMPATHETIC NERVOUS SYSTEM (SNS) AND THE PARASYMPATHETIC NERVOUS SYSTEM (PNS).THE SYMPATHETIC NERVOUS SYSTEM RELEASES THE HORMONES (CATECHOLAMINES-EPINEPHRINE AND NOREPINEPHRINE) TO ACCELERATE THE HEART RATE

Discuss the relationship between mitosis and cytokinesis. what would be the result if one happened without the other ?
DENIUS [597]
If mitosis occurred without cytokinesis, the cell would contain two nuclei and twice the DNA. If cytokinesis occurred without mitosis , one of the new cells would lack DNA and a nucleus altogether. The cell cycle is regulated by signals both inside and outside of the cell.

Answer:

The citric acid cycle is fundamental to produce the energy needed for aerobic cell metabolism, thereby mutations in the enzymes involved in this metabolic pathway would be lethal to the individual

Explanation:

In aerobic organisms, the citric acid cycle (also known as the Krebs cycle), is a key metabolic pathway used to remove electrons and uses them in the electron transport chain in order to generate adenosine triphosphate (ATP), the energy currency of the cell. The citric acid cycle depends on eight enzymes that oxidize acetyl-CoA into two molecules each of carbon dioxide (CO2) and water (H2O). Thus, the citric acid cycle is a series of chemical reactions that are key to breakdown carbohydrates, fats and proteins into CO2 and H2O in order to produce energy (ATP).

PolarNik [594]
Addition of a nucleotide onto a DNA is an endergonic reaction. In such reactions, the energy is provided by ATP.

ATP is the immediate source of energy for any endergonic reaction occuring in the body. Reactions such as addition of nucleotides are endergonic and anabolic reaction that is, these reactions consume energy which is provided by ATP.
