Sure, let's solve the given question step-by-step.
### Step 1: Analyze the blood glucose levels to determine when the person ate
We are provided with blood glucose levels at different hours of the day as follows:
- 07:00 - 4.2 mmol/L
- 08:00 - 4.2 mmol/L
- 09:00 - 8.4 mmol/L
- 10:00 - 7.6 mmol/L
- 11:00 - 7.1 mmol/L
- 12:00 - 5.1 mmol/L
- 13:00 - 4.8 mmol/L
- 14:00 - 3.1 mmol/L
- 15:00 - 4.1 mmol/L
- 16:00 - 4.3 mmol/L
- 17:00 - 4.6 mmol/L
### Step 2: Identify the maximum blood glucose level
Upon examining the values, we identify the highest blood glucose level:
- The maximum blood glucose level recorded is 8.4 mmol/L.
### Step 3: Determine the time corresponding to the maximum blood glucose level
The highest blood glucose level of 8.4 mmol/L was recorded at:
- 09:00.
### Step 4: Identify the likely time period / range of hours when the person ate
Blood glucose levels typically spike after a meal. Since the level is highly elevated at 09:00, it is most likely that the person ate before this time. Given the sudden spike, the meal was probably consumed between 08:00 and 09:00.
### Final Answer
- The person most likely ate between 08:00 and 09:00.
This means that the peak in blood glucose can be attributed to food consumption just before 09:00.

### Additional Questions
#### 2.1 (a) Name the two hormones involved in the normal homeostatic control of blood glucose levels
1. Insulin
2. Glucagon
#### 2.1 (b) Organ in the human body that secretes the hormones named in QUESTION 2.1(a)
- The pancreas secretes both insulin and glucagon.
### Summary of answers
1. The person most likely ate between 08:00 and 09:00.
2.1 (a) The two hormones involved in the normal homeostatic control of blood glucose levels are insulin and glucagon.
2.1 (b) The pancreas is the organ that secretes these hormones.
