a chemical reaction in livings organisms that releases energy from glucose

is a sugar that travels in the blood and is supplied to cells for respiration

is a stored form of glucose found in liver and muscle cells

a hormone secreted by the pancreas when blood glucose is too high, lowering blood glucose levels

a hormone secreted by the pancreas when blood glucose is too low, increasing blood glucose levels

Insulin, glucagon and the control of blood sugar level

Biology

The human endocrine system

Insulin and the control of blood sugar level

Type 1 and type 2 diabetes

Adrenaline, thyroxine and negative feedback

Pupils will learn more about photosynthesis in producers, including a two-stage model of the process and the requirements and products of each stage.

Pupils learned how the components of the human nervous system enable us to respond quickly to changes outside and inside our bodies.

This unit explores hormonal control by the endocrine system, including blood sugar regulation by insulin and glucagon, and the roles of thyroxine and adrenaline. It covers the importance of maintaining a stable internal environment and compares types 1 and 2 diabetes and their treatments.

Coordination and control: hormones and the human endocrine system

Which organ in the body detects changes in blood glucose concentration?

What process regulates the internal conditions in the body for optimum enzyme activity?

Match the hormone to the condition in which they are secreted. 

Eating causes an increase in blood glucose concentration.

The pancreas detects the increase in blood glucose concentration.

The pancreas secretes insulin into the blood.

Insulin targets the liver and muscle cells.

Blood glucose levels decrease back to normal.

Put these steps in order to show what happens after eating a meal. 

What do liver and muscle cells store glucose as?

Glycogen in the liver cells is converted into glucose.

Glucose in blood is stored as glycogen in the liver.

Which statements are true when blood glucose is too low?

What is the name of the sugar that is a reactant for respiration?

Which gland in the endocrine system is circled in this image?

The pancreas is a gland in the endocrine system, what does it secrete?

Match the activity to the effect it has on blood glucose concentration. 

In which sub-cellular structure does aerobic respiration take place?

Insulin, glucagon and the control of blood sugar level
