"Hitting the wall" with low-carb

Along with potassium depletion, low-carb diets can cause fatigue to set in due to used up glycogen stores. A low-carb diet, for example, might cause a high-mileage runner to “hit the wall” (1). Generally endurance athletes practice carb loading simply to fill up those glycogen stores to ensure lasting energy (1).

Low-Carb Quick Weight Loss Doesn’t Hold Water or Electrolytes

Alright, so you can lose weight fast with a low-carb diet. The lack of carbs will send the liver and muscles for their glycogen storage using up water and stimulating increased production of urine, or polyuria (1). Along with the osmotic diuresis, or increased urination, will be loss of sodium and potassium (1-2). Couple thatContinue reading “Low-Carb Quick Weight Loss Doesn’t Hold Water or Electrolytes”

Adrenal Cortex’s Aldosterone

No, aldosterone is not a new dietary supplement to pump you up the size of Arnold. It’s a hormone made up by your adrenal glands to help you hold onto sodium and rid off potassium whenever needed (1). How is aldosterone released? Particularly it begins with the electrolyte-fluctuation-sensitive kidneys (1). They stimulate aldosterone production byContinue reading “Adrenal Cortex’s Aldosterone”

What’s the most important part of the cell?

The earliest cell is thought to have emerged at least 3.8 billion years ago at a time when the environment was anaerobic in nature (1-2). It is suggested that simple organic molecules formed and gave rise to a self-replicating RNA that found itself within a phospholipid membrane (2).    The evolution of metabolism began withContinue reading “What’s the most important part of the cell?”

Trust a biochemist

At the molecular level of life matters may be small and energy gains and losses seemingly insignificant, but a broad understanding of biochemistry leads to profound, larger conclusions of cell biology and the energy of which is ultimately the existence of life. Just as the smallest ingredient such as a dash of salt can change the flavor of a recipe, the cell can be affected by the slightestContinue reading “Trust a biochemist”

The reason why hemolytic anemia probably exists

Hemolytic anemia Within the cytoplasmic matrix of a red blood cell occurs an anaerobic pathway of glucose catabolism known as glycolysis consisting of 10 reactions (1). The enzyme that catalyzes the last reaction is pyruvate kinase (1). The reaction is one of two that produces ATP and also pyruvate, the molecule generally converted to acetylContinue reading “The reason why hemolytic anemia probably exists”

How does stuff happen anyway?

Activation Energy A sling shot metaphor can be used to help understand activation energy. In endothermic reactions—like the force used pull the rubber strip of a sling shot—activation energy is the energy invested to raise reactant molecules to an “elevated” intermediate state. In exothermic reactions—like the force of letting go of the rubber—activation energy is also the energy required toContinue reading “How does stuff happen anyway?”
