**Transition Temperature of Membranes**

**Definition:**
What is meant by the transition temperature of a membrane? The transition temperature is the temperature at which a membrane undergoes a phase change from a solid-like state to a more fluid state. This transition is crucial for the functionality and permeability of biological membranes.

**Factors Affecting Transition Temperature:**
List the two characteristics of the fatty acids in a biological membrane that affect the transition temperature:
1. **Length of Fatty Acid Chains**: Longer chains usually increase the transition temperature.
2. **Degree of Unsaturation**: Unsaturated fatty acids have double bonds that introduce kinks, lowering the transition temperature and increasing membrane fluidity.

**Related Tips:**
- For accessing the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).
