Explanation / Answer

Phospholipase C

Catalyze formation of second messenger Diacylglycerol

Precursor of Diacylglycerol

Pip2

Second messenger associated with prevention of fertilization of an animal egg by multiple sperm cells

Calcium ions

Primary signal that activates platelets

Thrombin

Calcium ion activated protein that regulates other protein activity

Calmodulin

Hormone acting over long distances

Endocrine hormones

Monomeric G protein

Ras

Adenylate cyclase

Catalyze formation of cAMP from ATP

Pertussis toxin

Inhibition of Gi

Necessary for the activation of heterotrimeric G-proteins

GTP
