the answer is c hope this helps
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
<h3><u>Answer;</u></h3>
Biogeochemical cycles
<h3><u>Explanation</u>;</h3>
- <em><u>Biogeochemical cycles are cycles through which earth's elements undergo chemical reactions that build molecules, destroy molecules, and change molecules into other molecules, reusing the same atoms over and over.</u></em> These cycles includes a variety of chemical, geological and biological processes.
- The major biogeochemical cycles include; water cycle, carbon cycle, nitrogen cycle and oxygen cycle. These cycles function to conserve and recycle matter which is part of living organisms.
