Starches
Optimum enzyme temperature appeared to be the same as body temp
37 C
When the environment is too hot, enzymes
Are denatured and therefore do not work at all
Enzyme that will hydrolyze lactose
Lactase
Extreme temps tend to have the following effect on enzymes
eliminate the effect
Enzyme that acts upon starches
amylase
When the environment is too cold the enzyme
work normally when brought to an optimum temp
Protein that serves as a biological catalyst to speed up a reaction
enzymes
Factors that effect enzymatic activity
Ph, Salinty, Tempature
Why does starch solutions go from dark to clear after the addition of amylase
Eliminating the enzymes
DNA replication occurs in theS phaseMitosis results in the formation ofDiploid cellsMeiosis results in the formation ofHaploid cellsNuclear division is known asKaynesisDivision of the cytoplasm is calledCytokensisNon-mitotic phase of mitosis when the cell is resting or producing protiensInterphasePhase of mitosis in which the chromatin condenses to form chromosomesProphasePhase of mitosis chatcterized by the placement of the centromeres at the equatorial platemetaphasePhase of mitosis in which the sister chromatids separate and migrate toward the poles of the cellAnaphasePhase of mitosis in which the daughter chromosomes are found at the poles and the nuclear membrane is reformedTelophaseEnd products include alcohol or lactic acidAnerobic respirationWhat is the general PH of water7Causes soreness in the muscle cellLactic acidEnd products of animal respirationCaron dioxide, water, ATP (heat)Plants utilize both O2 and CO2 in performing respiration.
