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
True, a lot of cultivated fields use fertilizers that can be harmful to fish
A roller coaster is fastest at the front of the train. The shorter the hill the roller coaster climbs, the greater its kinetic energy. Potential energy is converted to kinetic energy as the roller coaster goes down the hill. No conclusion can be made from this evidence
