homeostasis is the regulation of the internal conditions to maintain optimum conditions for enzyme action and all cell functions

a chemical reaction in living organisms that releases energy from glucose

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

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

a stored form of glucose found in liver and muscle cells

Insulin and the control of blood sugar level

Combined science

The human endocrine system

Type 1 and type 2 diabetes

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?

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

What is the name of the hormone that the pancreas secretes if blood glucose levels are too high?

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?

Insulin causes glycogen to be converted into glucose.

Exercising and fasting decreases blood glucose concentration. 

If respiration rate increases then blood glucose concentration decreases.

Storing blood glucose as glycogen will increase blood glucose levels.

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

Which of the following is a biological catalyst?

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

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

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