5. #2 What do you think you are made of?
#1 The chemical formula for water is H2O. The H stands for Hydrogen and the O stands for oxygen. If you do not get enough water you will dehydrate , have organ failure, and then expire.

Is the element that makes up most of the human body
Gold if it is 100% Au atoms is a pure element,
but the human body is made
of molecules and compounds in cells.

10. are examples of nutrients

11. STORE ENERGY FOR THE CELL AND OTHER JOBS DO NOT MIX WITH WATER
MOLECULE CONTAINS SUGAR,
STRACH, OR FIBER.
SIMPLE CARBS = 1 OR A FEW SUGARS
COMPLEX CARBS=MANY SUGAR or Starches
FAT MOLECULE OR SIMILAR, SUCH AS WAXES AND STERIODS.
USED AS A SOURCE OF ENERGY AND FOR ENERGY STORAGE
MOLECULES THAT CARRY INFORMATION IN THE CELL
TELLS . 1 TYPE IS DNA FOUND IN ALL CELLS. DNA TELLS
CELLS WHICH MOLECULES TO MAKE SUCH AS PROTEINS.
NUCLEOTIDE TELLS ORDER OF AMINO ACID AND BUILDS
SPECIFIC PROTEIN
MADE OF SMALLER NUCLEOTIDES
MADE OF SMALLER AMINO ACIDS
PROTEINS BREAK DOWN INTO THE SMALLER AMINO ACIDS WHICH THEN REGROUP TO MAKE NEW PROTEINS WHICH
BUILD AND REPAIR BODY STRUCTURES AND REGULATE BODY PROCESSES. ENZYMES ARE PROTEINS THAT CATALYZE OR SPEED UP REACTIONS.

14. Phospholipid Bi-Layer- Head is hydrophilic
11 PICTURE USED TO EXPLAIN HOW
PHOSPHOLIPIDS FORM A BARRIER
BETWEEN WATER IN THE CELL AND WATER
OUT OF THE CELL
Hydrophilic ATTRACTED TO WATER
Bi layer 1 side
Hydrophobic REPEL WATER
Hydrophilic ATTRACTED TO WATER
Bi layer 2nd side
Phospholipid Bi-Layer-
Head is hydrophilic
Hydrophilic – ATTRACTED to water
Head is outer part of cell membrane
Tail is hydrophobic
Hydrophobic – REPELS water
tail points inward

15. Hydrophobic REPEL WATER

17. Hydrophobic REPEL WATER OUT OF THE CELL TOO MUCH WATER IS N
THE CELL SO AS THE
HEADS ATTRACT

THE TAILS WILL REPEL
THE WATER
PREVENTING
WATER FROM

REPEL
IN THE CELL TOO
MUCH WATER
SO TAILS WILL
REPEL MORE WATER

18. EXPLAIN IN YOUR NOTEBOOKS HOW THE BI-PHOSPHOLIPID LAYER OF THE CELL MEMBRANE WOULD HELP RESTORE HOMEOSTASIS T0 THE CELLS?

19. 12 Hydrophilic head ATTRACTED TO WATER Hydrophilic Head ATTRACTED TO
Hydrophobic tail
REPELS WATER
14 A PLUG ON A BECAUSE WHEN IT IS IN THE WATER STAYS IN THE TUB BUT WHEN IT IS OUT THE WATER GOES OUT OF THE TUB, MORE WATER CAN BE ADDED TO KEEP A HOMEOSTASIS EVEN FLOW AND IF TOO MUCH IS ADDED THERE IS A DRAIN HOLE TO LET IT OUT UNDER THE SPICKET

20. Make up the phospholipid bi layer of the cell membrane
If looked at individually C and H make up the tail of the phospholipid layer
17 Lipids – are fats that store energy
Carbohydrates-are sugars that are quick energy
Proteins-made of AA build, repair, & regulate
Nucleic Acids-carry information like DNA
H2O in and out of cell

21. Smallest unit one atom of a pure substances is an element
2 or more atoms of the same or different elements bonded
An atom is a pure substances (an element). Two or more atoms are a
Molecule.
5 Lipids – are fats that store energy
Carbohydrates-are sugars that are quick energy
Proteins-made of AA build, repair, & regulate
Nucleic Acids-carry information like DNA
Refer to prior slide for question #11

22. An atom can only be one element, An atom is pure. The picture has two
7 and 8
An atom can only be one element,
An atom is pure.
The picture has two
Different types of atoms
so it is a
Molecule and a compound.
Water is 2/3 of the mass of the cell.
Water moves in and out of the cell via
the bi phospholipid cell membrane
Uses active transport which
Requires energy in a process called osmosis to move water

23. Concentration in cell
Lower than out of cell
So osmosis moves water
Into cell
Concentration in homeostasis
Concentration in cell
higher than out of cell
So osmosis moves water
Out of cell
Concentration in cell
Lower than out of cell
LIKE IN SALTY ENVIRONMENT
So osmosis moves water
Into cell
