Cell The plant cell is seemingly less complicated then the animal cells. Having the necessary nucleus which holds the cells DNA and produces ribosomes that help in the synthesis of proteins. Surrounding the nucleus is the rough and smooth endoplasmic reticulum. The two help break down and store materials. Rough stores and transports synthesized proteins‚ while smooth stores and transports synthesized lipid‚ steroid hormones‚ and other materials. Small‚ but useful organelles within the cell are

named Glyoxysomes because they were found to contain enzymes of the Glyoxylate cycle. Definition Any of the membrane-bound‚ ovoid or spherical‚ granular cytoplasmic particles containing enzymes and other substances‚ which originate in the endoplasmic reticulum of vertebrate liver and kidney cells and other cells‚ and in protozoa‚ yeast‚ and many cell types of higher plants. Avarage Size 0.2 - 1.5 micrometers in diameter Function Microbodies contain enzymes that participate in the preparatory

posttranslational modification. A preprotein is a form that contains a signal sequence (an N-terminal signal peptide) that specifies its insertion into or through membranes‚ i.e.‚ targets them for secretion.[1] The signal peptide is cleaved off in the endoplasmic reticulum.[1] Preproproteins have both sequences (inhibitory and signal) still present. In protein synthesis‚ a succession of tRNA molecules charged with appropriate amino acids are brought together with an mRNA molecule and matched up by base-pairing

that can contaminate the rest of the cell vacuoles are needed. Vacuoles are bubbles inside the cell where materials can be stored. Nutrients and other material need a way to travel around a cell. The superhighway that does this job is called endoplasmic reticulum or E.R. The E.R. is a collection of membranes that allow materials to travel around the cell. Another way materials move around the cell is through the cytoplasm. The most important part of the cell is the nucleus. It is the brain of the cell

The Central Dogma. This hypothesis was described by Crick in 1958. In 1953‚ Watson and Crick were the first to determine the true crystalline structure of DNA‚ using model building and then X-ray crystallography. Once the DNA structure was determined‚ the mechanisms behind inheritance‚ information flow‚ and gene function fell into place. Overall the flow of information is depicted as: DNA --> RNA --> protein. Both DNA and RNA can be replicated (i.e. DNA is synthesized from DNA‚ and RNA from RNA)

http://www.scientificpsychic.com/fitness/carbohydrates1.html http://themedicalbiochemistrypage.org/carbohydrates.html Glucose is consumed in the diet and is required by the bodily tissues and the brain as a source of energy. The smooth endoplasmic reticulum (ER) in the liver and muscle cells synthesise glucose into glycogen and store this as an energy reserve in the cytoplasm. When this energy is required by the body‚ the smooth ER can quickly convert it back into glucose and release it into
