Step 1
Which row of the table shows the endocrine gland and hormone involved in the control of blood glucose concentration?
Answer
The correct row is D, which shows the pancreas and insulin. The pancreas is the endocrine gland that produces insulin, a hormone that helps to regulate blood glucose levels.
Step 2
Step 3
Describe two lifestyle changes person B should make to help control their blood glucose concentration.
Answer
-
Person B should adopt a healthy diet that is low in refined sugars and high in fiber, focusing on whole grains, fruits, and vegetables to help control blood glucose levels.
-
Engaging in regular physical activity, such as daily exercise or walking, can improve insulin sensitivity and enhance overall glucose control in people with type 2 diabetes.
Step 4
Which row of the table shows the type or types of respiration that use glucose?
Answer
The correct row is A. Both aerobic respiration and anaerobic respiration utilize glucose. Aerobic respiration occurs in the presence of oxygen, while anaerobic respiration occurs when oxygen is not available.
Step 5
Explain the trend shown in Figure 12.
Answer
The trend observed in Figure 12 indicates that as the speed of running increases, the respiration rate also increases. This is because higher physical activity levels demand more energy, requiring the body to metabolize more oxygen and glucose to produce ATP through aerobic respiration. When the person is sleeping, the energy demand is minimal, resulting in a lower respiration rate. In contrast, running quickly requires significant energy, leading to a notable increase in respiration rate, reaching 130 kJ per minute.
