Biology

Calorie- amount of energy required to raise 1 liter of water 1 degree celsius
Nutrient- a food substance in food required by living things to keep it alive

Organic Molecules:
Carbohydrates- simple sugar & complex sugar
Proteins
Lipids

Proteins->Amino Acids->New Proteins (amino acids go through dehyrdation synthesis to become new proteins)

New Proteins used for:

• in charge of movement
• chemical reaction (enzymes)
• plan B if there are no carbohydrates
• transport things in and out of the cells

Lipids are broken down and used for:

• insulation for bodies & cells
• storage
• absorb things
• hormones

Carbohydrates are broken down to make energy (ATP) using the process of cellular respiration, or stored in long chains called polysaccherides. Starches from plants; glycogen from animals.

Descibe organic molecules:

• contains carbon
• found in living things
• usually large

List examples of organic molecules:

• carbohydrates
• proteins
• nucleic acids
• lipids

What is a monomer?

• building blocks/sub-units to make macromolecules

What is a polymer?

• many monomers put together

How do monomers relate to polymers?

• monomers make up polymers

What is dehydration synthesis?

• the process by which a polymer is make by removing water
