- which is true of the adaptive immune response? it is always activated even before an "invasion" by an antigen occurs. it is in

volved with destroying body cells that have been infected with a pathogen. it reacts the same regardless of the type of antigen. it denies entry to the body and limits the spread of pathogens. it causes the release of complements.

The figure below shows the relative acceleration factors for pepsin, an enzyme found in the stomach, and trypsin, an enzyme foun
solniwko [45]

Enzymes are biocatalysts which increase the rate of biochemical reactions without undergoing any change themselves. It binds to the substrate forming the enzyme substrate complex and forming the product. The acceleration factor of enzymes is the factor by which the enzyme increases the rate of the reaction.

Pepsin and trypsin are enzymes involved in the breakdown of proteins in the stomach and the small intestine respectively. Enzymes function best at a particular pH called the optimum pH. Pepsin is found in the stomach with an acidic environment and function best at a pH range of 2-3. Small intestine has a pH between 7-8 and Trypsin secreted by the pancreas into the small intestine functions best at a neutral or slightly alkaline pH of 7-8.  Thus, the catalytic activity of the enzymes is maximum at its optimum pH.

Which component of dna makes up the language of genetic code?
loris [4]

Answer:

nitrogenous bases (adenine, guanine, thymine, uracil, cytosine) which are part of the nucleotides

Explanation:

The genetic code is the set of rules within genetic material that carries information about products that have to be synthesized (usually proteins).

During the process of translation (protein synthesis) code in mRNA (formed during the transcription of DNA) is read thanks to ribosome and tRNA. Transfer RNA (tRNA) molecules carry amino acids (for protein formation) and read the mRNA three nucleotides at a time and that happens within the ribosome. Those nucleotide triplets on mRNA are called codons and they specify which amino acid will be added next during protein synthesis.  

The genetic code is expressed in a simple table with 64 entries.

Identify the correct statement about the resting membrane potential of a cell. Group of answer choices
Pie

Answer:C

Explanation:

Resting Membrane Potential (RMP) is the charge difference represented as voltage difference across a nueronal cell membrane at rest.

It has a value of -50 and -75mV.

Graphically it represents the flat plateau at the last part of the curve of action potential (check the attachments)

In a normal resting cell after Action potential ;for example nuerone,the intercellular layer has more potassium ions, while the extracellular layer has more Sodium ions .

These ions have special channels called sodium and potassium channels for movement in and out of these ions by active transports.

The movements of these ions across the membranes generated electrical potential difference for action potential.
