What does a nucleus do? - correct answer It contains genetic material and controls the activities of the cell What does cytoplasm do? - correct answer It's a gel-like substance where most of the chemical reactions happen. It contains enzymes that control these chemical reactions What does a cell membrane do? - correct answer It holds the cell together and controls what goes in and out What do mitochondria do? - correct answer These are where most of the reactions for aerobic respiratio...

UNC Biol 205 Exam 2 Questions With Verified Answers when cells respond to an extracellular signal, they most often convert the information carried by this molecule from one form to another. What is this process called? - answersignal transduction When does signal transduction begin? - answerwhen the receptor on a target cell recieves and incoming extracellular signal and then produces intracellular signaling molecules that alter cell behavior extracellular signal molecules, released loca...

Why is cell signalling complex? - -not isolated pathways -all work together What is intracellular signalling? - a set of linked biochemical events that connect a specific biological stimulus with a specific cellular response What sorts of cell behaviours are controlled with communication between cells or environment? - their ability to... -survive -divide -migrate -differentiate -die

What are the 5 well-known enzyme-linked cell surface receptors? - correct answer1. Receptor Guanylyl Cyclase: produces cGMP 2. RTK: phosphorylate tyrosine residues leading to association of signalling molecules and cascade 3. TK Associated Receptors: associate with proteins having TK activity 4. Receptor Tyrosine Phosphates: Removes phosphate on tyrosine residues 5. Receptor Serine/Threonine Kinases: phosphorylate specific Serine/Threonine residues on IC signalling molecules How are RTK...

what is the ECM? - Answer-the non-cellular component present within all tissues and organs what is the ECM composed of? - Answer--composed of collagen I and elastin -fundamentally composed of water, proteins and polysaccharides -a complex network of proteins and polysaccharides what is the ECM secreted by? - Answer-secreted locally by cells and remain closely associated with them what does the ECM provide? - Answer--provides structural, adhesive and biochemical signalling support -not only...

What is T2DM?Insulin resistance and reduced insulin production causing high blood sugar levels What are the two components of T2DM?Insulin resistance & beta cell dysfunction / death How is beta cell compensation compared in diabetic and non diabetic patients?NONDIABETIC: Beta cell compensation to increase function and mass to increase insulin secretion DIABETIC: Beta cell de-compensation results in reduced beta cell function and mass so less insulin secretion What can cause insulin ...
