4 OSI Transport Layer 4.1 Roles of transport Layer 4.1.1 Purpose The Transport layer provides for the segmentation of data and the control necessary to reassemble these pieces into the various communication streams. Its primary responsibilities to accomplish this are: Tracking the individual communication between applications on the source and destination hosts Segmenting data and managing each piece Reassembling the segments into streams of application data Identifying the different applications

Active transport: requires that a cell expend energy to move molecules across a membrane against the solute’s concentration gradient (the side where it is more concentrated) Feedback inhibition: Metabolic reaction is blocked by its products. A product acts as an inhibitor of one of the enzymes in the pathway to regulate metabolism. Centriole: a structure in an animal cell composed of microtubule triplets arranged in a 9+0 pattern. An animal usually has a pair of centrioles within each of its centrosomes

Electron Transport Chain The first step in the electron transport chain process is for the NADH2 produced during glycolysis‚ the intermediate step‚ and the citric acid cycle to be attracted to Complex I (FMN ·FeS)due to its high affinity for NADH2. This attraction pulls NADH2 to Complex I (NAD dehydrogenase) and the two electrons from H2 are pulled off by the FeS (ferrous sulfate) leaving two H+ ions and NAD+. These molecules repel each other and this results in the NAD+ being recycled

Cell Respiration Respiration is the process by which organisms burn food to produce energy. The starting material of cellular respiration is the sugar glucose‚ which has energy stored in its chemical bonds. You can think of glucose as a kind of cellular piece of coal: chock-full of energy‚ but useless when you want to power a stereo. Just as burning coal produces heat and energy in the form of electricity‚ the chemical processes of respiration convert the energy in glucose into usable form. Adenosine

Pex7p Transport Role As previously stated‚ the location of the mutation causing the lethal RCDP1 phenotype has been narrowed down to the 10-exon PEX7 gene. wt PEX7 is translated as a cytosolic import receptor Pex7p‚ responsible for binding enzymes destined for the peroxisomal matrix marked by the N-terminal peroxisome-targeting signal 2 (PTS2). In a normal cell‚ the Pex7p receptor has a PTS2 receptor region that recognizes and binds the PTS2 of the localized protein in the cytosol‚ necessary for
