Fed vs. Fasted
After eating a meal, the liver increases this process to store glucose.
What is glycogenesis?
These pancreatic cells release glucagon.
What are alpha cells?
This hormone lowers blood calcium and promotes bone deposition.
What is calcitonin?
This process converts glycogen into glucose.
What is glycogenolysis?
This term includes all chemical reactions occurring in the body.
What is metabolism?
During fasting, this hormone increases as blood glucose falls.
What is glucagon?
This hormone causes the liver to convert glucose into glycogen.
What is insulin?
This hormone increases calcium reabsorption by the kidneys.
What is PTH?
This process produces glucose from non-carbohydrate sources.
What is gluconeogenesis?
BMR is the energy used by the body under this condition.
What is rest?
Which would NOT normally increase during fasting: glycogenolysis or glycogenesis?
What is glycogenesis?
Excess of this hormone can cause hypoglycemia.
What is insulin?
PTH acts directly on these two major tissues.
What are kidneys and bones?
Breakdown of stored triglycerides into fatty acids is called this.
What is lipolysis?
The brain normally uses this as its primary energy source.
What is glucose?
A traveler cannot eat much and begins using fat for fuel. His liver increases production of these alternative fuels.
What are ketone bodies?
This hormone primarily targets the liver and stimulates glycogenolysis.
What is glucagon?
PTH increases intestinal calcium absorption indirectly by activating this substance.
What is vitamin D / calcitriol?
During fasting, amino acids can serve as substrates for this glucose-producing pathway.
What is gluconeogenesis?
This organ is a major site of glycogen storage, gluconeogenesis, and ketogenesis.
What is the liver?
During severe fasting: glucagon rises, lipolysis rises, gluconeogenesis rises, and ketone bodies rise. what is true and or false in these statements?
What is "all statements are correct"
Insulin stimulates glucose uptake in muscle and fat by moving this transporter to the plasma membrane.
What is GLUT4?
This hormone lowers blood calcium by decreasing bone resorption and promoting calcium loss from the kidneys.
What is calcitonin?
This pathway converts fatty-acid-derived substrates into ketone bodies during prolonged fasting.
What is ketogenesis?
Thyroxine/T4 increases this measure of resting energy expenditure.
What is basal metabolic rate?
