Front

What is the transport form of carbohydrates in the body?

Back

Glucose is the primary transport form of carbohydrates in the body, used by cells for energy.

Front

What is homeostasis?

Back

Homeostasis is the process by which the body maintains a stable internal environment despite changes in external conditions.

Front

What role does hemoglobin play in red blood cells?

Back

Hemoglobin carries oxygen from the lungs to the tissues of the body and returns carbon dioxide from the tissues back to the lungs.

Front

Which gland secretes hormones that regulate blood glucose levels?

Back

The pancreas secretes hormones such as insulin and glucagon that regulate blood glucose levels.

Front

What organ stores glycogen?

Back

The liver stores glycogen, which is a form of energy reserve in the body.

Front

Define the term 'glycogen'.

Back

Glycogen is a polysaccharide that serves as a form of energy storage in animals, primarily found in the liver and muscles.

Front

What is the function of insulin?

Back

Insulin is a hormone produced by the pancreas that helps lower blood glucose levels by facilitating the uptake of glucose into cells.

Front

What is the function of glucagon?

Back

Glucagon is a hormone produced by the pancreas that raises blood glucose levels by promoting the conversion of glycogen to glucose in the liver.

Front

Explain the concept of negative feedback in the body.

Back

Negative feedback is a regulatory mechanism in which a change in a physiological variable triggers a response that counteracts the initial change, helping to maintain homeostasis.

Front

What is the difference between positive feedback and negative feedback?

Back

Positive feedback amplifies a response or process, while negative feedback reduces or counteracts a response to maintain stability.
