Where does translation always start? correct answers cytoplasm Do proteins destined for the nucleus (eg TF) also get translated in the cytoplasm? correct answers Yes, they must exit the nucleus to get translated and then get transported back into the nucleus What strategies do you think the cell can use to get proteins to the right place within the cell? correct answers - protein tagging What mechanisms do cells use to transport proteins to the right place within the cell? correct answe...

What are the main differences between first and second generation antihistamines - ANS - Benadryl (1st) crosses BBB - ant muscarinic effects Claritin (2nd) does not cross the BBB due to water solubility and does not have ant muscarinic effects - selective Eicosanoids - ANS - lipids derived from arachidonic acid Prostaglandins, thromboxane’s, and leukotrienes Similar to hormones Where is arachidonic acid located? - ANS - fatty acid tails of the cell membrane What does phospholipa...

EXSC 330 - Exam 1 Questions and Answers Latest Update Graded A+ **What is ATP (adenosine triphosphate) and its function in cells?** - ATP is the main energy source used by cells for most of their work. It stores potential energy extracted from food in its bonds, and energy is released when the outermost phosphate bond is broken by the enzyme ATPase. **What forms ADP in the ATP cycle?** - ADP forms when ATP combines with water (H2O). **What is the Phosphocreatine (PCr) system?** - The...

primary function of Krebs cycle - ️️to remove hydrogens and the energy associated with those hydrogens from various substrates involved in the cycle P/O ratio - ️️ratio of phosphagen bonds formed to oxygen atoms consumed Process of oxidative phosphorylation - ️️passes electrons from oxidation of a fuel source (CHO, fat, PRO) to NADH or FADH2, and finally to oxygen to produce ATP - slow but high ATP yield ATP - ️️(adenosine triphosphate) main energy source that cells use for...

CMMB 403 Midterm 1 Question and answers 100% correct CMMB 403 Midterm 1 Describe the RTK signal transduction pathway when activated by the FGF ligand FGF ligand dimerizes RTK receptor. Receptor is phorphorylated and attracts adaptor/GEF. GEF begins phosphorylation cascade: GEF to Ras to Raf to Mek to Erk to TF. TF transcribes gene Describe the JAK-STAT pathway when activated by FGF FGF ligand dimerizes RTK. JAK2 proteins cross-phosphorylate. Both JAK2s phosphorylate a STAT5 (which is...
