EVERY CELL’S NOW


“For each body cell, there is a now”
The human body is an astonishing hub of activities, with so many processes concurrently taking place. Today, energy yielding processes are the focus.



Listing the main energy-consuming and utilizing cellular processes in the body will take but a few seconds; they include:
Ø  Glycolysis: the breakdown of glucose to pyruvate with the release of useable energy. A metabolic process which occurs in almost all the body’s cells. Glycolysis yields 2 net molecules of energy in form of Adenosine Triphosphate (ATP)
Ø  KrebsCycle: also known as the Citric Acid Cycle, the Krebs cycle is the final common pathway for the oxidation of carbohydrate, lipid and protein- in short, all energy sources- since they can all be converted into acetyl-CoA, one of the metabolic substrates of this cycle. 10 ATP molecules are formed per turn of the citric acid cycle.
Ø  Gluconeogenesis: Process of energy production i.e glucose synthesis, from non-carbohydrate sources such as amino acids, lactate and  glycerol. This process promotes weight loss when an individual consumes low-carbohydrate food substances.
Ø  Glycogenolysis: Breakdown of glycogen into glucose in times of energy need. Results in ATP generation.
Ø  Ketogenesis: Involves ketone body formation from fatty acids. These ketone bodies serve as fuel for extrahepatic tissues (i.e. tissues outside the liver). Beta-oxidation of fatty acids generate large uantities of ATP also.
Well, that was a bit explanatory/ quite exhaustive, wasn’t it?
These processes are important because they help in minute-to-minute, day-to-day generation of energy for the body’s use.
They teach us one vital lesson:
Ø  The fact that energy was generated for utilization yesterday does not guarantee today’s energy availability. It still depends on your present nourishment. You cannot keep depending on previous knowledge stores e.g. in your field, for your past doesn’t settle your future!
Cells, that make up our living bodies understand the principle of now, let us emulate them as well, giving yield to ATP as needed, and replenishing our stores actively.

SALIENT LESSONS FROM THE CORONARY ARTERIES The coronary arteries provide blood supply to the heart, the blood pump. Some of its duties are outlined and deductions are saliently made from them. 1.       REPLENISHMENT: The first lesson to take from the coronary artery is that it replenishes the heart. While performing the work of pumping blood to other tissues, the cardiac muscle is replenished by means of its 2 coronary arteries. 2.       DIRECTLY SOURCED: The coronary arteries, unsurprisingly, take origin from the aorta, the main artery leaving the left ventricle, carrying oxygenated blood to all branch arteries of the human body. Thus, it originates from the principal source of maximally oxygenated blood; this points to the fact that it reveres impartation and not opinions. 3.       PERFUSION: The coronary arteries ensure that blood gets to every part of the heart by means of its several branches. Branc...

#MONDAY’S PROSE THIS CHILD; ON THE ROAD

Through my myopic eyes, a fleeting image of a little boy is formed on my retina A little boy in a little suit, Treading the familiar bushy routes before him The boy had neither escort nor directives And surely, he needed none For a 4 yr old on the road possesses more maturity than a 10 year old in ‘comfort’ Swiftly, she navigated through cars held in traffic An adventurous smile tugging at her split lips Providing snacks for impatient car-owners And though panting from car-chasing, She had a visible life of passionate content She probably planned to get off the street, Forsake her hypothetical ‘street-urchin boyfriend’, Give up this demeaning way of living, But I feared she wouldn’t! She hadn’t been wired to get off the street And sadly, she was too content to stage a forced exit. Children on the road and teenagers of the road, Not choosing to be this vulnerable Yet hooded and shrouded in the cold, Filled with shreds of hope that the fut...

DOKITA

 EPISODE 3 ‘Oya sorry now, we’re almost there.’ Felix kept saying as he partially carried his dear friend.  She wouldn’t hear the last of this episode once it was over, that much he knew! ‘Awww…you don’t know how painful awww… this is’ ‘Sorry, sorry’ ; he kept saying So they eventually got to the ER and after pulling out her card, used ‘medical student connection’ to see the resident that was on call in Internal Medicine unit. ‘Hello dear’ , Dr. Brown said, looking keenly at the girl that was almost doubled over in pain ‘I think you should lie down on that couch’ ‘What exactly is the problem?’ ‘She just started complaining about her abdomen about half an hour ago’ ‘Oh’. ‘Can you point to where exactly the pain started?’ he asked ‘Here’ . Linda pointed to the area around her umbilicus. ‘Have you had any episode of vomiting?’ ‘No sir’ Felix answered spontaneously. ‘You must be her boyfriend, right?’ Dr.Brown asked, with a mischievious grin ...
