AP Bio Ras Protein Paper The Ras proteins are a family of proteins that belong to a class of proteins called the small GTPase’s. They belong to a large super-family of proteins known as "low-molecular weight G-proteins". They are used to transmit signals throughout a cell using transduction. They strengthen the signals conveyed by linking them to a chemically irreversible process such as the cleavage of GTP. Ras proteins are usually in the “off” state where the GDP is bound to the site.

Sarah Khan Bivins-5th April 20th‚ 2013 Protein Synthesis Every day‚ you take in an abundance of different biomolecules; one of them being proteins. Have you ever wondered how proteins are made? They don’t just grow from a tree or fall from the sky‚ they are made through a process called protein synthesis. Protein synthesis is broken up in two two steps: transcription and translation. Transcription starts inside the nucleus when the DNA is unzipped by helicase. Following that‚ the mRNA nucleotides

Protein powder is bad because it contained a lot of additive‚ sugar and too much protein. Although natural protein provide immune system defense for the body and also contain antioxidant components‚ however‚ that does not mean that protein shake or protein powder has the same function as the natural protein. As time goes by‚ protein powder has become essential for muscle builder to consume. People drink protein shakes or take pills while they are working out or after performing intense exercise.

methyl group from streptozotocin to the DNA molecule causes damage‚ which along a defined chain of events‚ results in the fragmentation of the DNA. Protein glycosylation may be an additional damaging factor . In the attempt to repair DNA‚ poly(ADP-ribose) polymerase (PARP) is overstimulated. This diminishes cellular NAD+‚ and subsequently ATP‚ stores the depletion of the cellular energy stores ultimately results in beta cell necrosis. Although streptozotocin also methylates proteins ‚DNA methylation

The Great Metabolic Race Organisms are constantly undergoing various chemical reactions and pathways that enable for them to maintain life. These pathways are part of metabolism‚ involving catabolism (break down of organic nutrients for extraction of useful) and anabolism (energy dependent conversion of small precursor molecules in complex molecules); some of which are energy coupled to provide energy efficiency. This intermediate coupling is due to the “energy currency” within the body‚ known as
