Question

Which of the following is not an extracellular matrix role of carbohydrates?

A) Structural support
B) Cell signaling
C) Energy storage
D) Lubrication

Answer 1

The extracellular matrix (ECM) is a network of carbohydrates and proteins that provides support to cells. Carbohydrates in the ECM contribute to structural support and cell signaling, but not energy storage.

Step-by-step explanation:

The extracellular matrix (ECM) is a complex network of carbohydrates and proteins that provides support and structure to cells. While carbohydrates play important roles in the ECM, energy storage is not one of them. Carbohydrates in the ECM primarily contribute to structural support and cell signaling. They help cells keep their shape and transmit signals within the tissue.
