Science Final 2.1(Ch)

Front 1

what are carbohidrates? what for the do for the cell?

Back 1

•they provide the cells with energy
•simple carbohidrates are sugers, coplex carbohidrates are starch and cellulose
• when more suger is made that needed it's stored as starch
•cellulose makes up the cell wall

Front 2

what are lipids and what do they do for the cell?

Back 2

•fats, oils, and waxes found in living things
•simple lipids are used by the cell for energy and structual suport
•many lipids consist of glycerol bonded to fatty acids
•lipids cannot mix with water

Front 3

lipids con.

Back 3

make up the membraines surrounding the cell and orginells
•the head is hidrophilic(likes water) and the tail is hidrophobic(does not like water)

Front 4

protiens; what they are

Back 4

•made of amino acids
•amino acids contain carbon, oxygen, hydrophen, nitrogen, phospherous, and sulfer
•structer and function is determend by how the amino acids are aranges

Front 5

protiens; what they do for the cell

Back 5

as enzimes they control chemical reaction, provide suport and groth, help mucells and movement, help bloud fight infections, helps blood deliver oxygen
• carry out most of the chimical activity in the cell

Front 6

steps of protien synthesis

Back 6

1st DNA is copied as RNA in the neculas and messenger RNA enters cytoplasm
2nd transfer RNA brings in amino acids acording to to the code in pairs of 3
3rd peptide bonds form between polypeptides and tranfer RNA leaves
4th process continues intill a long chain is built
5th long chain combines and twists and coils
6th twisting continues and disulfide bonds form

Front 7

nuclaic acids; what they are and how they help the cell

Back 7

hold instuction for the maintnence and groth and reproduction of the cell
•two types DNA and RNA
•subunits are nuculatides
•DNA provides info for making all protiens and is copied in a code as RNA
•RNA enters cytoplasm
