physical science

• store genetic information.
• store genetic information


  nucleic acids
• made up of carbon, hydrogen, oxygen, and nitrogen.

  protein
• molecules that contain carbon, hydrogen, oxygen and they function related to energy

  carbohydrates and lipids
• elements common to all four biomolecules

  carbon, hydrogen and oxygen
• they are classified into a single category of biological molecules because they help to regulate metabolism

  enzymes, vitamins and hormones
• build lean muscles and strengthen tendons and ligaments

  protein
• provides energy


  carbohydrates
• provides energy, structure, support, strength, and moderates fluids balance in living organism


  carbohydrates
• high in protein but low in carbohyrates will give a person headache and fatigue because it will make his blood low in glucose
• excess cholesterol in our arteries is not desirable because
• it is a molecular group that carries and passess on the hereditary information of an organism
• are biomolecules that are significant features of the cell membrane
• are made up of the elements, hydrogen, carbon and oxygen
• are organic molecules that provide quick source of energy
• are nutrients group that are used in the composition of waxes and are responsible for insulation of some organism
• is a molecule tht does nor belong to the classification of lipids
• are referred to as the building blocks of protein
• is a polysaccharide that is stored in the liver and muscles when converted carbohydrates are excessively consumed
• it is a monosaccharide that is in usee of dextrose
• good example of a saturated fats
• referred as the blueprint of life
• considered as one of the four elements of protein
• is a major fibrous protein found in connective tissues such as tendons, ligaments, skin, cartilage and cornea of the eyes
• polypeptide taht store oxygen in the muscles
• not a part of a nucleotide
• the reaction must collide ewith enough energy and be in the right positions
• molecules react by colliding together, must occur with certain minimum amounts of energy,and the greatee the number of effective collisions the faster the reaction rate
• this can also increase the collision between particles thus increasing the reaction rate
• this increases the rate of reaction because it increases both the frequency and the energy of particle collision
• this increases the surface areas thus increasing the reaction rate
• when the surface area decreased, the reaction rate also decrease because
• the time it takes for a reaction to occue
• this increases the rate of reaction because it reduces the activation energy of the reactants
• when surface area is decreased, teh reaction rate also decrease because
• by this, the rate of reaction in a closed container will also increase
• how does a chemical reaction occur
• this must have both a reactant and a product
• for a collision to be effecitve
• amino acids
