What is a constitutive enzyme?
Give this one a try later!
An enzyme that is continually made because it is necessary for life. It is
independent of how many substrates are present.
What causes mutations?
Give this one a try later!
errors in DNA replication, radiation, mutagenic chemicals
What is translation?
,Give this one a try later!
is the process of translating the sequence of a messenger RNA (mRNA)
molecule to a sequence of amino acids during protein synthesis. (Happens
in the cytoplasm and ribosomes do all of the work)
How do you measure by dry weight?
Give this one a try later!
Dehydrate the organisms and determine their mass. This is mainly used for
samples that cannot be counted with the other methods.
what is a product?
Give this one a try later!
A product is what the substrate is turned into. (it is the result of the enzyme-
facilitated reaction)
What major molecules are involved in the translation process?
Give this one a try later!
Ribosomes, mRNA, tRNA, ribosomal RNA, amino acids
, What is the optimum temperature for growth in mesophiles?
Give this one a try later!
15-45C
How do you measure by metabolic activity?
Give this one a try later!
Measure the amount of metabolic product made by the sample. More
product, more cells.
How does temperature affect enzyme activity?
Give this one a try later!
Enzymes have an optimum temperature and when the temperature is too
high, the enzyme becomes denatured and when the temperature is too
low, the activity lessens as well.
What is saprophytism?
