FAQ: What Is The Biology Of Type 2 Diabetes?

Type 2 diabetes is primarily the result of two interrelated problems: Cells in muscle, fat and the liver become resistant to insulin. Because these cells don’t interact in a normal way with insulin, they don’t take in enough sugar. The pancreas is unable to produce enough insulin to manage blood sugar levels.

What is type 2 diabetes A level biology?

In type 2 diabetes, the person’s body cells no longer respond to insulin produced by the pancreas. This includes the liver, which becomes less able to convert glucose into glycogen. Type 2 diabetes is more common in older people. It can be managed by a carbohydrate controlled diet and an exercise regime.

What is the biology of diabetes?

Diabetes is a disease that occurs when your blood glucose, also called blood sugar, is too high. Blood glucose is your main source of energy and comes from the food you eat. Insulin, a hormone made by the pancreas, helps glucose from food get into your cells to be used for energy.

What is type 2 diabetes How does it develop?

Type 2 diabetes develops when the pancreas makes less insulin than the body needs, and the body cells stop responding to insulin. They don’t take in sugar as they should. Sugar builds up in your blood. When cells don’t respond to insulin, this is called insulin resistance.

What causes type 2 diabetes biology?

Type 2 diabetes is primarily the result of two interrelated problems: Cells in muscle, fat and the liver become resistant to insulin. Because these cells don’t interact in a normal way with insulin, they don’t take in enough sugar. The pancreas is unable to produce enough insulin to manage blood sugar levels.

What is the difference between Type 1 and type 2 diabetes biology?

Type 1 diabetes is an autoimmune disease. It occurs when the insulin-producing islet cells in the pancreas are completely destroyed, so the body can’t produce any insulin. In type 2 diabetes, the islet cells are still working. However, the body is resistant to insulin.

What are the biological causes of diabetes?

The main things that lead to it are:

  • Obesity or being overweight. Research shows this is a top reason for type 2 diabetes.
  • Impaired glucose tolerance.
  • Insulin resistance.
  • Ethnic background.
  • Gestational diabetes.
  • Sedentary lifestyle.
  • Family history.
  • Polycystic ovary syndrome.

What are the 3 types of diabetes?

There are three main types of diabetes: type 1, type 2, and gestational diabetes (diabetes while pregnant).

  • Type 1 Diabetes. Type 1 diabetes is thought to be caused by an autoimmune reaction (the body attacks itself by mistake) that stops your body from making insulin.
  • Type 2 Diabetes.
  • Gestational Diabetes.

What is type 2 diabetes GCSE?

Type 2 diabetes is a serious condition where the insulin your pancreas makes can’t work properly, or your pancreas can’t make enough insulin. This means your blood glucose (sugar) levels keep rising.

Is type 2 diabetes genetic?

Type 2 diabetes has a stronger link to family history and lineage than type 1, and studies of twins have shown that genetics play a very strong role in the development of type 2 diabetes. Race can also play a role. Yet it also depends on environmental factors.

When does type 2 diabetes develop?

Type 2 diabetes most often develops in people over age 45, but more and more children, teens, and young adults are also developing it.

Is type 2 diabetes irreversible?

Summary: People with type 2 diabetes can reverse the condition through a low calorie diet. A body of research putting people with Type 2 diabetes on a low calorie diet has confirmed the underlying causes of the condition and established that it is reversible.

Does type 2 diabetes require insulin?

People with type 2 diabetes may require insulin when their meal plan, weight loss, exercise and antidiabetic drugs do not achieve targeted blood glucose (sugar) levels. Diabetes is a progressive disease and the body may require insulin injections to compensate for declining insulin production by the pancreas.

What is type 2 diabetes sugar level?

Fasting blood sugar test. Results are interpreted as follows: Less than 100 mg/dL (5.6 mmol/L) is normal. 100 to 125 mg/dL (5.6 to 6.9 mmol/L) is diagnosed as prediabetes. 126 mg/dL (7 mmol/L) or higher on two separate tests is diagnosed as diabetes.

Which type of diabetes is genetic?

Type 2 diabetes can be inherited and is linked to your family history and genetics, but environmental factors also play a role. Not everyone with a family history of type 2 diabetes will get it, but you’re more likely to develop it if a parent or sibling has it.

What Happens During Transcription In Biology?

Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). The newly formed mRNA copies of the gene then serve as blueprints for protein synthesis during the process of translation.
