What kinds of membranous structures can be seen on electron micrographs of the cell interior? - Vesicles, network of membrane-bound channels, stacks of flattened, membrane-bound sacs (e.g. golgi apparatus, RER) What pathways of vesicle trafficking through the cytoplasm have been discovered? - motor proteins pull vesicles along tracks of microtubules and microfilaments What substances of the biosynthetic pathway are made in the Golgi apparatus? - lipids and carbohydrates What is the synthe...

Generic Cell Signalling Pathway - Signal --> Receptor --> transduction cascade --> target --> response Endocrine Signaling - Target Cell far from secretory cell paracine signaling - Target adjacent to secretory cell ligand - A molecule that binds specifically to another molecule, usually a receptor. =Signal

They are initially post-translationally inserted into the endoplasmic reticulum (ER) lumen. D. They are co-translationally inserted into the ER lumen. - Answer D. They are co-translationally inserted into the ER lumen. Feedback: Fig. 13-1 Which of the following accurately describes targeting ...

training effect - Correct Answer-An increase in functional capacity of muscles and other bodily tissues as a result of increased stress (overload) placed upon them. Homeostasis - Correct Answer-The automatic tendency to maintain a relatively constant internal environment. Metabolism - Correct Answer-The total of all the chemical and physical processes by which the body builds and maintains itself (anabolism) and by which it breaks down its substances for the production of energy (catabolis...

NSCI 175 Exam 3 (2023) || Questions & Answers (Graded A+) NSCI 175 Exam 3 (2023) || Questions & Answers (Graded A+) Draw a diagram to compare the pattern of neural communication between neurons of the secretory hypothalamus, network of neurons of the ANS, and diffuse modulatory systems - ANSWER - Hormones have more widespread effects in the brain and body, can target many sites in the body, and have often longer lasting effects compared to traditional neurotransmitters. Secretory Hypothal...

How would you use epifluorescence microscopy to examine the localization of a chimeric GFP fusion protein in a living cell? The λexcite for GFP is 395 nm & emission is 509 nm? - Answer Irradiate or illuminate the cell at 395 nm and view it at 509 nm (Fig. 4-9) Indirect immunofluorescence microscopy utilizes: - Answer A fluorescently tagged secondary antibody that binds by its CDR to the Fc region of a primary antibody bound by its CDR to an epitope on its corresponding antigen. (Fig. 4...

Heritability correct answers - Has to be a germ line mutation - Mutation in a somatic cell (tissues) cannot be passed down. Things in the gene can. Adhesion proteins correct answers attach cells to neighboring cells or provide anchors for the internal filaments and tubules that give stability to the cell chaperone proteins correct answers assist in folding other proteins Clathrin correct answers protein that coats the inward-facing surface of the plasma membrane and assists in the form...
