Effects of temperature and pH on cell permeability & effects of substrate concentration on enzymes in proteins lab answers

Abstract Proteins are very complex structures and have many variables that affect their function. This lab examined some of those variables. For the first part beef liver, which contains the enzyme catalase, was added to solutions of different concentrations of the substrate hydrogen peroxide. The second and third sections tested the effects of temperature and…

Genetic Recombination in Eukaryotes: Meiosis

Sexual reproduction: production of offspring; union of male and female gametes Gametes: eggs and sperms cells in animals Sexual reproduction depends on Meiosis; specialized process of cell division; recombines DNA sequences, produces cells with half the number of chromosomes in somatic cells. (chromosome= reduction) Fertilization: nuclei of egg/ sperm fuse; producing zygote (# chromosomes typical…

Mendel and Genetics

Blending theory of inheritance: hereditary trait blend evenly in offspring through mixing of parent’s blood. Mendel studied heritable characteristics called characters; plant color and seed shape. Variation in character= Trait Monohybrid cross between to heterozygous parents (Dr x Dr) F1 generation will yield phenotypic ration of 3:1 (1/4 getting PP or pp, or ½ getting…

Cell Cycles: Interphase, Mitosis, Cytokinesis

Cell Cycle: nuclear division, cytokinesis Parental cell: genetic copies of parental cell 3 process: checks/ regulators for each step to ensure timely progression, replication process to synthesis DNA into two copies, interwoven “cables” and “motors” of mitotic cytoskeletons. Chromosomes: nuclear units of genetic information; DNA molecules combined with proteins. In eukaryotes, heredity information of nucleus…
