HELP!! What are some examples for facilitated diffusion?

1 answer:

By definition: Facilitated diffusion<span> is the process of spontaneous passive transport of molecules or ions across a cell's membrane via specific transmembrane integral proteins.~Google

An example, the only I can really think of:
Polar and large molecules normally can't cross the lipid bi layer using simple diffusion, it usually has to be </span>Facilitated diffusion

The following sequence of double stranded DNA encodes a hypothetical protein called GEN in a bacteria. Transcription starts at a

vaieri [72.5K]

Answer:

A) AUG GAG GGU

B) N-MET-GLU-GLY-HIS

C) 10 amino acids

D) The stop codon here is UAA, instead of UAG. If a tryptophane residue is added where the stop codon is, the GEN polypeptide would be longer

Explanation:

First we must obtain the the complementary chain or mRNA

A) AUG start codon is complementary to DNA TAC triplet, and GAG is complementary to CTC, and GGU to CCA (running from left to right towards 5'DNA direction (AAGCGGATACCTCCCAGTAGATGCTCCGGGGCTAGTGATTTCGAAC-5)

B) TAC corresponds to Methionine, GAG to Glutamate, GGU to Glycine, and CAU to Histidine

C) UAA is the stop codon, that is complementary where the DNA triplet is ATT. From AUG to UAA, we can have 10 amino acids transcribed

D) If a trp is included where the stop codon is UAA, then the mRNA would be longer with a consequent traduction of a longer GEN polypeptide

Peroxidase is a protein. What is this protein’s function, and how did it get its name?.

Olin [163]

Answer:

Most peroxidases are ferric heme proteins; one notable exception being the glutathione peroxidase, which is a selenium-containing enzyme. They are present in virtually all living species.

Protein has many roles in your body. It helps repair and build your body's tissues, allows metabolic reactions to take place and coordinates bodily functions. In addition to providing your body with a structural framework, proteins also maintain proper pH and fluid balance.
