When blood glucose levels rise following a meal, the following events occur. Arrange these events in the appropriate sequence. (a) Glucagon is secreted. (b) Glycolysis replenishes ATP supplies. (c) Glucose is absorbed by cells. (d) The liver releases glucose into the bloodstream. (e) Glycogen synthesis (glycogenesis) occurs with excess glucose. (f) Blood levels pass through normal to below normal (hypoglycemic). (g) Insulin levels rise.

Key Concepts

Glycogenesis

The process of synthesizing glycogen from excess glucose. This is a storage mechanism that occurs in the liver and muscle cells, allowing the body to store surplus energy for future needs.

Glycolysis

A key metabolic pathway that breaks down glucose into pyruvate, generating ATP in the process. Glycolysis provides cells with immediate energy needed for various functions, especially after glucose uptake.

Cellular Glucose Uptake

The process by which cells absorb glucose from the blood, mainly facilitated by insulin-regulated glucose transporters. This uptake supports cellular energy production through metabolic pathways such as glycolysis.

Glucagon

A hormone secreted by pancreatic alpha-cells when blood glucose levels fall below the normal range. It acts primarily on the liver to stimulate the release of stored glucose into the bloodstream, counteracting the effects of insulin and restoring blood glucose to normal levels.

Blood Glucose Homeostasis

This refers to the body's mechanism for maintaining blood glucose levels within a narrow optimal range despite fluctuations from food intake. It involves hormonal regulation that includes both the lowering of blood sugar following a meal and the raising of blood sugar when levels drop too low.

Insulin

A hormone produced by the pancreatic beta-cells in response to increased blood glucose levels. Insulin facilitates the uptake of glucose into cells, stimulates glycolysis to produce ATP, and promotes glycogenesis to store excess glucose, thereby reducing blood sugar levels.
