Erin Arroyo Lab report June 11‚ 2013 Biology 123 Professor K Title: Scientific Investigation of the Peroxidase Enzyme & Temperature Abstract: In this lab we tested the effect temperature has on the rate of enzyme activity. The way we figured this out was by taking four different temperatures and testing the different absorbance levels they produced every 20 seconds for two minutes straight using a spectrophotometer. The important part of this experiment was the temperature

important roles in progression of cells from G1 to S phase. CDK4 and CDK6 partner with the family of proteins that control the progression of cells through the cell cycle by activating cycling dependent kinases enzymes (a type of enzyme that transfers phosphate groups from high-energy donor molecules‚ such as ATP to specific substrates). Phosphorylation of the retinoblastoma releases transcription factors‚ inducing gene expression and metabolic changes that precede DNA replication‚ thus allowing the cell
