The image contains a worksheet on Blood Glucose Regulation (Homeostasis). Below are the answers to the questions based on standard biological facts regarding the endocrine system and blood sugar control.
Step-by-step reasoning for the answers:
1. Question 1: "In a healthy person, how does the body maintain blood glucose levels within a narrow range?"
* *Reasoning:* This process is called homeostasis. It involves the pancreas releasing hormones (insulin and glucagon) to adjust blood sugar levels.
* *Answer:* By the release of hormones (insulin and glucagon) from the pancreas.
2. Question 2: "What is the normal range for blood glucose levels in a fasting state?"
* *Reasoning:* Standard medical reference ranges for fasting blood sugar are typically between 70 and 100 mg/dL.
* *Answer:* 70–100 mg/dL.
3. Question 3: "When blood glucose levels are high, which hormone is released by the pancreas?"
* *Reasoning:* High blood sugar triggers beta cells in the pancreas to release insulin to lower it.
* *Answer:* Insulin.
4. Question 4: "What is the primary function of insulin in the body?"
* *Reasoning:* Insulin acts like a key, allowing glucose to enter cells from the bloodstream to be used for energy or stored.
* *Answer:* To lower blood glucose levels by facilitating the uptake of glucose into cells.
5. Question 5: "What happens to excess glucose in the liver when insulin levels are high?"
* *Reasoning:* The liver stores excess glucose as a polysaccharide called glycogen (glycogenesis).
* *Answer:* It is converted into glycogen for storage.
6. Question 6: "What is the term used to describe the condition where blood glucose levels are too low?"
* *Reasoning:* "Hypo" means low, "glycemia" refers to sugar in the blood.
* *Answer:* Hypoglycemia.
7. Question 7: "What is the term used to describe the condition where blood glucose levels are too high?"
* *Reasoning:* "Hyper" means high.
* *Answer:* Hyperglycemia.
8. Question 8: "Which hormone is responsible for raising blood glucose levels when they are too low?"
* *Reasoning:* When blood sugar drops, alpha cells in the pancreas release glucagon to signal the liver to release stored sugar.
* *Answer:* Glucagon.
9. Question 9: "What is the primary source of glucose for the body during fasting or starvation?"
* *Reasoning:* During fasting, the body breaks down stored glycogen in the liver (glycogenolysis) and later creates new glucose (gluconeogenesis). The primary immediate source is glycogen.
* *Answer:* Glycogen (stored in the liver).
10. Question 10: "What is the role of the liver in regulating blood glucose levels?"
* *Reasoning:* The liver acts as a buffer. It stores glucose as glycogen when levels are high and releases glucose (from glycogen breakdown) when levels are low.
* *Answer:* It stores glucose as glycogen and releases glucose into the blood when needed.
11. Question 11: "What is the effect of exercise on blood glucose levels?"
* *Reasoning:* Muscles use glucose for energy during exercise, which generally lowers blood glucose levels.
* *Answer:* It typically lowers blood glucose levels (as muscles use it for energy).
12. Question 12: "What is the effect of stress on blood glucose levels?"
* *Reasoning:* Stress triggers the release of cortisol and adrenaline, which increase blood sugar to provide a "fight or flight" energy boost.
* *Answer:* It typically raises blood glucose levels.
13. Question 13: "What is the effect of alcohol consumption on blood glucose levels?"
* *Reasoning:* Alcohol can interfere with the liver's ability to release glucose, potentially causing hypoglycemia (low blood sugar), especially if consumed without food.
* *Answer:* It can cause blood glucose levels to drop (hypoglycemia).
14. Question 14: "What is the effect of certain medications (e.g., steroids) on blood glucose levels?"
* *Reasoning:* Steroids (corticosteroids) often increase insulin resistance and stimulate glucose production, raising blood sugar.
* *Answer:* They can raise blood glucose levels.
15. Question 15: "What is the effect of illness or infection on blood glucose levels?"
* *Reasoning:* The body releases stress hormones during illness to fight infection, which raises blood sugar.
* *Answer:* They typically raise blood glucose levels.
16. Question 16: "What is the effect of dehydration on blood glucose levels?"
* *Reasoning:* Dehydration leads to a higher concentration of glucose in the blood because there is less water volume.
* *Answer:* It can cause blood glucose levels to appear higher (concentration increases).
17. Question 17: "What is the effect of sleep deprivation on blood glucose levels?"
* *Reasoning:* Lack of sleep increases stress hormones and can lead to insulin resistance, raising blood sugar.
* *Answer:* It can raise blood glucose levels.
18. Question 18: "What is the effect of caffeine on blood glucose levels?"
* *Reasoning:* Caffeine can temporarily increase blood sugar or decrease insulin sensitivity in some people.
* *Answer:* It can temporarily raise blood glucose levels.
19. Question 19: "What is the effect of smoking on blood glucose levels?"
* *Reasoning:* Smoking increases insulin resistance, making it harder for the body to use insulin effectively, leading to higher blood sugar.
* *Answer:* It can raise blood glucose levels (increases insulin resistance).
20. Question 20: "What is the effect of age on blood glucose levels?"
* *Reasoning:* As people age, they may become less active and gain weight, and the body may become less efficient at processing glucose, leading to slightly higher baseline levels or increased risk of diabetes.
* *Answer:* Blood glucose levels may increase with age due to decreased insulin sensitivity.
