1. Intercellular Definition
NUTRIENTS / ENZYMES
1. Take a look at this link - there is a basic intro to some of the most common nutrients eg. lipids, animo acids, they also explain enzymes very clearly.

​
2. NUTRIENTS - FOOD TESTS
 a) Benedict's Test for Reducing Sugars

 b) Benedict's Test for non-reducing sugars

 c) Iodine Test for Starch

d) Biuret Test for Proteins
​
e) Ethanol Emulsion Test for Fats and Oils


3. Biological molecules
​Carbohydrates, proteins and lipids are biological molecules. They can be detected using chemical and physical tests.

TRANSPORT IN HUMANS

Formation of a fibrin clot


Why is the bicarbonate buffering system important?
When carbon dioxide is in the blood, it reacts with water to form bicarbonate (HCO3−) and hydrogen ions (H+). As the level of carbon dioxide in the blood increases, more H+ is produced and the pH decreases.
