Hb lab questions

  1. 1. HB lab<br />Question 1<br />Refers to the image below of a number of large nerve cell bodies surrounded by other supporting cells – you need to focus on the sub-cellular structure labelled A (ie. the dark red dot.)<br />a. Identify the structure labelled “A”b. What is the function of the structure labelled “A”?<br />1. Identify the cell component labelled “A”.2. What is term used to name the region of the cell labelled “B”.3. Within the region of the cell labelled “B” (but not resolvable in this image) name the organelle that produces ATP.4. Within the region of the cell labelled “B” (but not resolvable in this image) name the small organelle (about 25nm) that synthesises proteins.5. Within the region of the cell labelled “B” (but not resolvable in this image) name the organelle whose functions include sorting and packaging secretory products.6. Within the region of the cell labelled “B” (but not resolvable in this image) name the organelle that functions as the cells digestive system.7. Within the region of the cell labelled “B” (but not resolvable in this image) name the anastomosing network of membranes whose many functions include lipid metabolism and detoxification.8. Within the region of the cell labelled “B” (but not resolvable in this image) name the organelles that are membrane bound vesicles of various sizes containing material destined for degradation/digestion.9. Within the region of the cell labelled “B” (but not resolvable in this image) name the anastomosing network of membranes whose many functions include the synthesis of proteins for secretion. <br />1. Name the bright pink-stained structure labelled “A” (within the circular structure).2. What does the structure labelled “A” synthesize?<br />Question 4<br />1. What cell organelle produces ATP?2. What cell organelle sorts and packages synthetic products of the cell?<br />Question 5<br />a. Identify the structure labelled “A”<br />a. Identify the structure labelled “A”b. What is the function of the structure labelled “A”?<br />Question 7<br />a. Identify the structure labelled “A”b. What is the function of the structure labelled “A”?<br />Question 8<br />a. Identify the structure enclosed within the circle and labelled “A”b. Identify the structure labelled “B”c. Identify the structure labelled “C” ie. the pale region superimposed by the label “C”d. Identify the structure labelled “D”e. Identify the structure labelled “E”<br />Question 9<br />a. Identify the pale circular structure labelled “A”b. Identify the region of the cell labelled “B”<br />Question 10<br />a. Identify the dark material labelled “A”b. Identify the pale material labelled “B”c. Identify the region of the cell labelled “C”<br />Question 11<br />a. Identify the structure labelled “A”<br />Question 12<br />a. Identify the structure (small dot) labelled “A”b.
