Final answer:
Excess cholesterol does not contribute to adipose tissue. Adipose tissue stores fats such as fatty acids and triglycerides, which can be synthesized from excess glucose and amino acids. Cholesterol isn't directly stored as fat in adipose tissue.
Step-by-step explanation:
The molecule that does NOT contribute to adipose tissue is excess cholesterol. Adipose tissue primarily stores fats, which include fatty acids and triglycerides. Excess glucose in the body can lead to more pyruvate, which can then be converted into fatty acids and subsequently stored in adipose cells.
Similarly, excess amino acids can be converted to fatty acids and stored as fat. However, while excess cholesterol is related to fat metabolism and may contribute to cardiovascular diseases, it is not directly stored as fat in adipose tissue.
When glycogen stores are full, the liver converts additional glucose into fatty acids, which are then stored in the adipose tissue. These fatty acids are a significant component of adipose cells, which are dedicated to storing fat. In contrast, excess proteins and fats can produce glycogen or be used directly but are not the primary contributors to fat storage in adipose tissue.
