What macromolecules are in potatoes?
COMPLEX – Example: potato Potatoes are made up of starch (a complex sugar). Complex carbohydrates are called polysaccharides (poly means “many”). So plants store their energy as the complex carbohydrate called starch. Plants can also have a complex carbohydrate called cellulose.

Which biomolecule is found in pasta and bread?
1. Carbohydrates – sugars, starches (flour), grains. Carbohydrates can be found in almost all food sources. Rice, cereal, potatoes, fruits, pasta, vegetables, etc., have some kind of carbohydrate in them.
What macromolecules Cannot be in food?
Ten of these amino acids are called essential amino acids because they cannot be manufactured by our body and must be obtained from our food. The final type of macromolecule that we ingest into our bodies are lipids, also known as fats.
Which type of carbohydrate Cannot be broken down by the body?
Fiber is contained in many carbohydrates and cannot be digested by the body.
What happens when your body breaks down macromolecules?
Hydrolysis reactions break bonds and release energy . Biological macromolecules are ingested and hydrolyzed in the digestive tract to form smaller molecules that can be absorbed by cells and then further broken down to release energy.
What is most important hair growth?
Eating adequate protein is important for hair growth because hair follicles are made of mostly protein. A lack of protein in the diet has been shown to promote hair loss ( 1 ). Biotin is essential for the production of a hair protein called keratin, which is why biotin supplements are often marketed for hair growth.
