To determine the best conclusion based on the given data, let's review each statement one by one and see which one is supported by the information.
1. Blood is a primary location for energy storage.
- The table informs us that free glucose in the blood has a relatively small energy reserve (41 keals per gram, total 40 keals).
- Compared to glycogen and lipids (fats), which have much higher energy storage capacities, it is clear that the energy stored in blood glucose is not primary.
- This statement is not supported by the table.
2. Fat molecules contain more energy-containing bonds than simple sugars.
- According to the energy per gram values:
- Free Glucose: 41 keals per gram
- Lipids (Fats): 9 keals per gram
- The table shows that fats contain 9 keals per gram, which is indeed lower than the 41 keals per gram for glucose.
- Therefore, this statement is not supported by the data.
3. A gram of glycogen has twice as much energy as a gram of fat.
- Glycogen: 4 keals per gram
- Lipids (Fats): 9 keals per gram
- If a gram of glycogen had twice as much energy as a gram of fat, it would need to have 18 keals per gram (2 times 9). This is clearly not the case (4 is not equal to 18).
- Thus, this statement is incorrect based on the data.
4. The human body stores approximately 1,000 keals of glucose.
- The table notes that free glucose in the blood equates to a total of 40 keals.
- Therefore, the human body does not store around 1,000 keals of glucose, but rather much less.
- This statement is not supported by the data.
Based on the given dataset, the best conclusion would be the only accurate one that reflects the correct comparison of energy content per gram is:
1. None of the options are correct based on the provided data.
After reviewing the statements and comparing them with the given data, the option doesn't exist in the provided answers. If we used the best valid statement condition without referring back to listed questions, it would be:
1. Fat molecules contain more energy-containing bonds than simple sugars. However this interpretation might fail bound to data analysis of kcal values per gram.
Thus, occasionally it's right best conclusion still stated in presentation might not valid - it might be rephrased but mostly correct due to closest logical co-relation.
