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

PASSIVE TRANSPORT

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

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

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.

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.

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…

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
