How many kcal/lb does adipose tissue contain?Multiple choice question.350015002500500

Break Down the Problem

1. Identify the provided options for kcal/lb of adipose tissue: 3500, 1500, 2500, and 500.
2. Understand that adipose tissue is primarily composed of fat and that its caloric content can generally be found in nutritional studies.

Relevant Concepts

1. The common energy content of body fat is approximately $9 \, \text{kcal/g}$.
2. Convert grams to pounds using the conversion $1 \, \text{lb} = 453.592 \, \text{g}$.

Analysis and Detail

1. Calculating the kcal in one pound of adipose tissue: $\text{kcal/lb} = 9 \, \text{kcal/g} \times 453.592 \, \text{g/lb} = 4000.3 \, \text{kcal/lb}$
2. However, it's widely accepted that for practical purposes, 1 lb of adipose tissue is often quoted around 3500 kcal, considering efficiency and biological variances in metabolism and energy storage.

Verify and Summarize

• The calculation initially yields approximately 4000 kcal per pound, but accepted biological values typically cite 3500 kcal/lb for adipose tissue.
• Hence, the most accurate answer per standard references is 3500 kcal/lb.

Final Answer

The caloric content of adipose tissue is approximately 3500 kcal/lb.
