### Important Facts:
* **Enzyme:** The enzyme **maltase**, located on the brush border microvilli of the small intestine wall, breaks down maltose into two individual units of glucose.
* **Absorption:** Once converted into simple glucose, it is readily absorbed through the intestinal walls into the bloodstream for energy.
* **Salivary Start:** While starch breakdown begins in the mouth via salivary amylase, actual maltose conversion to glucose happens exclusively in the small intestine.

### Important Facts:
* **Value:** One knot is equal to **one nautical mile per hour**, which translates to exactly **1.852 km/h** (approx. 1.15 mph).
* **Historical Origin:** Sailors used to throw a log tied to a knotted rope into the sea. They counted how many knots passed through their hands in a set time period (measured with an hourglass).
* **Primary Application:** Standardized unit for ships, boats, submarines, and aircraft velocity.
