Carbohydrates (Test #2)
What are the 5 steps of our body recovering from hypoglycemia?
1. Starts w/ too little blood sugar 2. Pancreas senses that there isn't enough sugar in the blood and then secretes the hormone glucagon 3. Glucagon then tells the liver to break down glycogen -> glucose and then put that glucose into the blood 4. Gluconeogensis also makes new glucose from amino acids which happens in the liver 5. Normalization of blood glucose occurs... our glucose level rises back to our normal range
What are the 5 steps of our body recovering from hyperglycemia?
1. Starts w/ too much blood sugar 2. Pancreas senses the extra sugar in the blood and then releases insulin 3. The insulin then tells the fat, muscle, and liver cells to remove the extra sugar from the blood (the skeletal muscle and liver are told to take some of the glucose and store it as glycogen) 4. Glucose level will then decrease 5. Then we are back to our normal blood glucose level (normalization)
