CARBOHYDRATES!
Definition:
Carbohydrates provide body cells with the energy they need.
Carbohydrates are:
Polysaccharide- Starch, Cellulose, glycogen
Disaccharides- Maltose, sucrose, lactose
Monosaccharide- Galactose, fructose and glucose
Fun facts!
Excess carbohydrates in our body are turned into fats and glycogen. Glycogen is stored in the liver and the muscles. The fats are stored in the adipose cells underneth the skin. Fats are used for providing energy only if carbohydrate intake is low.
Equation:
Starch ----------------------> Maltose ------------>Glucose
(salivary amylase) (Maltase)

PROTEINS!!
Definition:
Proteins are the main substances used for the growth for new cells and the repair of damaged tissues. They provide energy when the body lacks carbohydrates and fats. Excess protein cannot be stored. It is toxic. It is removed mainly as urea in urine and in faeces.

Digestion In Animals
Question:
Does Animals store starch? What Happens when starch is digested?
Answer:
Although we eat starch, we do not store it. Starch will be digested into glucose. After digestion, excess glucose will be converted into glycogen and will be stored in the liver and muscles.
Reasons for eating:
-grow new cells and tissues
-repair damaged tissues
-provide energy for work, movement and to maintain body temperature
-Maintain body functions such as breathing and keeping the heart beating.

Question:
Is it healthier to eat raw food or cooked food?
Answer:
It is believed that raw food is healthier for the body than cooked or processed food. People who eat raw food wholly or largely claimed that eating raw food has numerous health benefits, including increased energy levels, clearer skin, better digestion, weight loss and reduced risk of heart attack. According to the Living and Raw Foods website, raw, uncooked foods are believed to contain essential food enzymes which help the digestion process without relying on the body to produce the enzymes that are lost through cooking. It is also thought that cooking (heating food above 46 degrees) destroys vitamins and minerals and that cooked foods take longer to digest and tend to allow partially digested fats, proteins and carbohydrates to clog up our digestive system and arteries.
