How do cells use a high-calorie molecule such as glucose?
Cells use high-calorie molecules like glucose through the process of cellular respiration. Glucose is broken down in a series of enzymatic reactions to produce ATP, which is the cell's primary energy source. This energy is then used for various cellular processes and functions.
What is During digestion excess glucose is stored in liver cells and muscle cells in what form?
Excess glucose is stored in liver cells and muscle cells in the form of glycogen. When blood glucose levels are high, insulin signals these cells to take up glucose and convert it into glycogen for storage. This glycogen can later be broken down back into glucose when energy is needed.
What is glycogenesis?
Glycogenesis is the process by which glucose molecules are converted into glycogen for storage in the liver and muscle cells. This occurs when blood glucose levels are high, usually after a meal, and helps to regulate glucose levels in the body. Glycogenesis is an important part of maintaining energy balance and blood sugar levels.
How do cells use a high calorie molecule such as glucose?
Cells break down glucose through a series of chemical reactions called glycolysis to produce energy in the form of ATP. This process involves converting glucose into pyruvate, which is then used in the mitochondria to generate more ATP through the citric acid cycle and oxidative phosphorylation. The energy produced from glucose metabolism is essential for cellular activities and functions.
If blood glucose levels are to high what hormone will this organ secrete?
If blood glucose levels are too high, the pancreas will secrete insulin. Insulin helps lower blood glucose levels by promoting the uptake of glucose into cells for energy production and storage.

What occurs in cells during respiration?
In essence, respiration uses glucose and oxygen to produce high energy molecules known as ATP.
What is the glucose sensor in B-cells Why?
glucokinase. glucokinase has a high km(low affinity for glucose) so glucokinase only phosphorylates glucose when blood glucose is high, such as after a meal. As such, it makes sense that this would be sensor for B-cells
What is glucose receptors?
The purpose of the glucose receptors is to detect blood glucose levels. The Islets of Langerhorn dispatch alpha cells to detect low blood glucose and beta cells to detect high blood glucose levels.
How molecules which cells use to store energy is made?
Cells store energy in the form of molecules such as ATP (adenosine triphosphate) through processes like cellular respiration. During cellular respiration, glucose is broken down in a series of biochemical reactions to produce ATP, which can then be used as an energy source by the cell. The energy produced from breaking down glucose is stored in the high-energy bonds of ATP molecules.

How does diffusion help take in oxygen and glucose?
Diffusion allows oxygen and glucose molecules to move from areas of high concentration, such as the bloodstream, to areas of low concentration, such as cells that need them for energy production. This natural process occurs across cell membranes, ensuring that the essential molecules reach their intended targets efficiently.
What would cause a rapid breakdown of glucose molecules?
A salmon jumping up a waterfall
What molecules has 90 times the energy of ATP?
The molecule with approximately 90 times the energy of ATP is phosphocreatine (PCr), which is used by cells to rapidly regenerate ATP during high-intensity activities like muscle contraction. PCr donates its high-energy phosphate group to ADP to form ATP in a reaction catalyzed by the enzyme creatine kinase.

The energy produced from glucose metabolism is essential for cellular activities and functions.
Which organ monitors concentration of glucose in the blood?
The pancreas monitors blood glucose levels through specialized cells called beta cells located in the islets of Langerhans. These cells secrete the hormone insulin in response to high blood glucose levels to regulate and maintain glucose concentration within a normal range.
