Molecules

Describe the shapes of molecules and how that is the foundation of biology.

Molecules are made up of one or two of the same or different atoms. Molecules can have different shapes from a straight to a curve shape, but it all depends on the atoms it contains. The shape of the molecule depends on repulsion between electron pairs. Molecules combine to form compounds, where they lose all their individual properties and are given new ones. The different type of molecules in a compound are demonstrated in the formulas. Molecules are the foundation of biology because they are are fundamental structure of cells which is needed in living things. Cells that help our living body to function and give us the ability to do the things we  are able to do today. Biology is study of living things in the world

Enzymes in Our Bodies

Enzymes are protein molecules which are catalysts, substances that speed up the process of a chemical reaction. Enzymes can be found in our bodies ad help us live, function, and work. Three are three types of enzymes that help living things maintain themselves : Metabolic Enzymes, Digestive Enzymes, and Food Enzymes. Digestive enzymes in our living bodies help break down food and turn it into proteins. Digestive Enzymes, in addition to this, help break down fats, carbohydrates and proteins in our body efficiently.  

There are 4 types of digestive enzymes in the human body: 

-Amylase
This enzyme is essential with helping us with the with the digestion of our carbohydrates. In addition to this it is an aid in diagnosing various pancreas or other digestive tract diseases.

-Lactose
This enzymes helps our body break down sugars , lactose, and anything with dairy products. This is enzyme helps  and is especially important to people who are lactose and tolerant.

-Lipase
This enzymes helps our body break down the fats that we consume each and everyday. It is produce in small amounts in our mouths and stomachs, and in larger amounts our pancreas

-Proteases
Proteases mare enzymes that help break down proteins in the human body.
They can be found:

• Chymotrypsin
• Pepsin
• Trypsin
