1. HOW DOES IT WORK?
By: Samantha, Dallas, Lindsey, Kira

2. PASSIVE TRANSPORT
 Cellular process in which substances move through
a cellular membrane with their own energy supply
directly by the cell or its membrane.

3. ACTIVE TRANSPORT
 Movement of a substance in or out of a living cell
requiring the use of cellular energy.
 The liquids inside and outside of cells have different
substances.
 means movement in the direction opposite that of
diffusion or movement from an area of lower
concentration to an area of higher concentration
 REQUIRES ENERGY

5. GROWTH
 Proteins are manufactured according to the cells
genetic code; functional proteins, the
enzymes, direct the synthesis of other molecules in
the cells and thus the production of larger
organelles also know G1 phase.
 After DNA is replicated the cell continues to grow by
means of protein synthesis and the resulting
synthesis of other molecules and various
organelles, and that’s the G2 phase.

6. GROWTH CONT.
 Nucleotides, influenced by newly synthesized
enzymes, arrange themselves along the open sides
of an “unzippered” DNA molecule, theraby creating
two identical daugher DNA moecules; produces two
identical sets of the cells genetic code, enabling the
cell to later split into two different cells,e ach with its
own complete set of DNA sometimes called the S
phase.

7. PROTEIN SYNTHESIS
 Protein syntesis begins with transpcriptoin, a
process in which an mRNA moecule forms along
one gene sequence of a DNA mocelute within the
cells nuceus. As it is formed, the mRNA moceule
separates from the DNA molecule, is edited, and
leaves the nucleus through the large nuclear pores.
Outside the nucleus, ribsome subunits attach to the
begging of the mRNA molecule and begin…

8. PROTEIN SYNTHESIS CONT.
 Translation, transfer RNA molecules bring specific
amino acids- encoded by each mRNA codon-into
place at the ribosome site. As the amino acids are
brought into the prper sequence, they are joined
together by peptied bonds to form long strands
called polypeptieds. Several plypeptied chains may
be needed to make a complete protien molecule
