The answer is c since a coccus is any spherical or roughly spherical bacterium.
Answer:
Explanation:
Gene expression can be define as a process that occur in every living cell of the organism. It is a process in which information carried by the gene is used for the synthesis of a functional gene product. These products are proteins, but from the non-coding regions of the gene products like transfer RNA (t-RNA) or small nuclear RNA (sn-RNA) can also be produced.
Answer:
E. Enzyme cleaves PIP2, forming DAG and IP3.
D. IP3 binds to a ligand-gated ion channel in the ER membrane.
A. Calcium ions flow through the ligand-gated ion channel.
C. Calcium ion concentration increases in the cytosol.
B. Calcium ions activate a protein, leading to a cellular response.
Explanation:
The enzyme phospholipase C which cleaves PIP2 into DAG and IP3 Is activated by the G protein once the histamine signaling molecule is received. IP3 moves to the cytosol to bond to IP3 gated calcium channel in the Endoplasmic reticulum membrane allowing for influx of Ca++ from the Endoplasmic reticulum membrane to the cytosol prompting a cellular response. The histamine's signal transduction pathway allows for amplification and regulatation of a signal at different points
