4. Aldosterone, the primary mineralcorticosteroid secreted by your adrenal cortex, is absolutely essential to your life. Without it, you will die within a week. It’s essential for Na+ and K+ balance. Because of sodiums osmotic effect, sodium balance is critical to maintaining the proper ECF volume and arterial blood pressure. This action is essential for life. Without aldosterone’s sodium and water-conserving effect, so much plasma volume would be lost in the urine that death would quickly occur. Maintaining potassium ion balance is also essential for homeostasis because changes in ECF K+ profoundly impact neuromuscular excitability, most importantly of the heart.
So when they say our brain can run off of 75% ketones, what does that mean? That Acetone is being turn into Acetyl-Co to power the mitochondria?
I’m taking biology 111 this year in college and our topic this week was cellular respiration.
I have a few questions for you. I’ve been on a ketogenic diet for 3 months now and have lost almost 40lbs. I’m always interested in what exactly happens in my body. What percentage of our body can run off of ketones? What’s the bare minimum of glucose you need? If I’m eating so little carbs, will my body take muscle tissue to use as fuel if I’m eating enough fat and protein? Is it true that cancer cells can’t run off of ketones?
So in diabetic ketoacidosis the problem is the body overproduces ketones because the cells are insulin resistant and can’t receive glucose so it switches to fats as fuel. But in regular ketosis induced by low carb intake, our body doesn’t overproduce ketones in non-diabetic individuals?
