What factors affect the rate of enzyme activity?
-Heat, temperature, &pHtemperature, pH level, concentration of enzyme, concentration of substrate( my sec.1 science book)
What are 3 factors which can influence the activity of an enzyme?
temperature, PH and concentration of substrate (reaction).
How is the binucleate condition of liver cells explained?
The presence of more than one nucleus, or a binucleate, usually signifies a larger than usual cytoplasmic mass must be regulated.
Difference between inducible and repressible operons?
The differences between these two types of operons are significant. In the repressible operon, The product is the regulatory metabolite and starts in the "on" position allowing RNA primase to unzip mRNA. Also the repressor protein only bings to the operator gene in the presence of the regulatory metablite. In the inducible operon, The reactact is the regulartory metabolite and starts in the off position blockig the primase from unzipping mRNA. The repressor protein only binds to the operator gene in the absence of the regulatory metabolite.

it is used as a bleaching agent but in the presence of moisture
What would be the likely outcome if you increased the concentration of substrate for an enzyme in the presence of a noncompetitive inhibitor?
No change in enzyme activity would be observed.

In what way does the presence of an atmosphere enhance conditions for life on Earth's?
An atmosphere allows for regulated temperature and with out regulated temperature life cannot stabilize and we would not be able to form life in the first place. Also it allows for certain chemical compounds to form and that allows life to exist.
What advantages did humans do to the ecosystem?
The presence of humans does not convey any advantage to the ecosystem. The most we can do is minimize the damage we cause.
How many molecules of ATP are gained by substrate-level phosphorylation from the complete breakdown of a single molecule of glucose in the presence of oxygen?
In substrate level phosphorylation, the ADP is phosphorylated directly by the transfer of phosphate group from substrate. If we consider glucose, then we get four substrate level phosphorylated ATPs, net gain of two in glycolysis and other two are formed when the two pyruvate molecules formed after glycolysis enter the TCA cycle.
In what way does the presence of an atmosphere enhance conditions for life on earth surface?
An atmosphere allows for regulated temperature and with out regulated temperature life cannot stabilize and we would not be able to form life in the first place. Also it allows for certain chemical compounds to form and that allows life to exist.
