Metabotropic receptors function by activating nearby G proteins and arereferred to as G-coupled or linked receptors. Various types of G proteins exist,each leading to distinct downstream outcomes. Stimulation of stimulatory Gproteins, i.e., Gs proteins, results in the production of CAMP, which can promotethe opening of different ion channels.Based on this, which of the following describes the decreased excitability ofmuscle cells with the activation of a specific Gs protein-linked receptor?Note: Pick all that apply.The activated ion channels were potassium (K+) gated channels, causinghyperpolarization and subsequently reducing the production of action potentials.The activated ion channels were sodium (Na+) gated channels, causing repolarizationand subsequently reducing the production of action potentials.The activated ion channels were chlorine (CI-) gated channels, causing depolarizationsince Cl- will leave the cell and subsequently reducing the production of actionpotentials.☐ The activated ion channels were chlorine (CI-) gated channels, causinghyperpolarization since Cl- will enter the cell and subsequently reducing the productionof action potentials.

The question asks which scenarios would lead to a decreased excitability of muscle cells due to the…

RTKs are receptors made of an extracellular ligand binding domain and an intracellular kinase domain (see image). Insulin binds to its RTK Insulin receptor, causing an increase in glucose absorption and storage in liver cells. EGF binds to its own RTK, EGFR and promotes cell growth through the Ras pathway. a) Explain why the same type of tyrosine kinase in two RTKs can lead to very different cellular responses. Give an example of potential cellular outputs for each of these two RTKs.

Which of the following is most likely an example of signaling through a transmembrane receptor? The influenza virus recognizes specific proteins on the surface of host cells, causing the entrance of genetic materials into the cytoplasm of the host cells. Low-density lipoproteins (LDL) bind to receptor proteins found on the membrane of receiving cells, triggering its internalization into the receiving cells. The binding of interleukin-6 (IL-6) to the interleukin-6 receptor causes the activation of protein kinases in the cytoplasm, activating the transcription factor NF-κB. The binding of aldosterone to the aldosterone receptor activates its transcription activity, leading to the transcription of genes that promote the uptake of ions and water.

A contributing factor to the development of arthritis is the inappropriate proteolytic destruction of the aggrecan component of cartilage by the proteolytic enzyme aggrecanase. The immune system signal molecule interleukin 2 (IL-2) activates aggrecanase; in fact, IL-2 blockers are sometimes used to treat arthritis. Studies were undertaken to determine whether inhibitors of aggrecanase could counteract the effects of IL-2. Pieces of cartilage were incubated in media with various additions and the amount of aggrecan destruction was measured as a function of time. What is the effect of adding IL-2 to the system? Aggrecan degradation remains the same. Aggrecanase activity is greatly reduced. Aggrecan degradation is greatly reduced. Aggrecan degradation is greatly enhanced. What is the response when an aggrecanase inhibitor is added in addition to IL-2? O Aggrecan degradation remains the same as when IL-2 was added. Aggrecan degradation completely stops. Aggrecan degradation is reduced to…
