<p>Two types of bulk transport common to most cells are:
1) gated and non-gated pathways
2) tight junctions and desmosomes
3) pinocytosis and phagocytosis
4) mediated phosphorylation</p>
<p>I think it's B. We learned about that a long time ago So I can't fully remember. I'm pretty sure it's not C,D. Tight junctions were if I remember correctly where to cells could transport things between themsevles.</p>
<p>thanks for the help...</p>
<p>My pleasure.</p>
<p>anyone else??</p>
<p>actually, i think it's 3, b/c bulk means big things, and pino and phagocytosis is how stuff (large) get in to the cell, and the tight junction is sounding like something in neurons, plus, if it's a junction then the substances diffuse in or out and i don't think bulky substance diffuse through anything :S</p>
<p>yea thats what i thought, b/c pino and phago are cellular "eating/drinking", so the particles must then be transported, thus bulk transport..</p>
<p>How about:
1. Which of these carbs constitues the bulk of dietary fiber?
1)starch 2) cellulose 3) glucose 4) fructose 5) chitin</p>
<ol>
<li> Members of a community which convert radiant energy into chemical bond energy are known as:
1)primary consumers 2)producers 3) secondary consumers 4) saprophytes 5) decomposers</li>
</ol>
<ol>
<li>I believe that's cellulose.</li>
<li>Producers.</li>
</ol>
<p>yea the first one-fiber is usually polysachs, thus cellulose, thanks</p>
<p>first question is pino/phagocytosis. the other 2 are right.</p>
<p>3 more...
1)The ATP produced as the result of glycolysis is the result of:
1)chemiosmosis 2)ionic diferentiation 3)substrate level phosphorylation 4)thylakoid synthetase</p>
<p>2)Which wavelengths of light would be most effective for the conversion of radiant energy into the chemical energy of organic compounds in plants?
1)orange red 2)yellow green 3) yellow blue 4) red blue 5)green blue</p>
<p>3)All of the following cell components are found in prokaryotic cells EXCEPT
1)DNA 2)Ribosomes 3)Nuclear envelope 4) Cell membrane 5) Enzymes</p>
<p>1) choice 1
2) choice 4 (you can see that here: <a href="http://www.biologie.uni-hamburg.de/b-online/e24/3.htm%5B/url%5D">http://www.biologie.uni-hamburg.de/b-online/e24/3.htm</a> - most light is absorbed in the red + blue areas)
3) choice 3</p>
<p>1)Which is the frozen desert? 1)taiga 2)tundra 3) chaparral 4) grasslands 5)temperate plains</p>
<p>2)The principle inorganic compound found in living things is 1)Carbon 2)Oxyg 3)Water 4)Glucose 5)Carbon dioxide</p>
<p>3)Metafemale syndrome, a disorder in which a female has an extra X chromosome, is the result of nondisjunction. The failure in oogenesis that could produce this would occur in 1)Prophase 1 2)Metaphase 1 3) Metaphase 2 4) Telophase 1 5) Anaphase 2</p>
<p>4)Crossing over permits scientists to determine 1)the chance for variation in zygotes 2)The rate of mutations 3)chromosome mapping 4) which traits are dominant or recessive 5)which traits are masked</p>
<p>anyone know these?</p>
<p>Aren't YOU supposed to be figuring these out?</p>
<p>lol im trying, my textbook is over 1000 pgs and my teacher blows</p>
<p>I seriously think it is answer 3.</p>
<p>Pinocytosis is cellular drinking and phagocytosis is cellular eating.</p>
<p>For the one about ATP and glycolysis, I believe it is answer 3, substrate level phosphorylation, chemiosmosis comes at a later state in cellular respiration as part of the electron transport chain, although chemiosmosis is the primary source of ATP in cellular respiration it is not how ATP is produced in glycolysis.</p>
<p>jesset, you're right</p>
<p>My feeble friends need biology help.</p>
<p>First question answer: (3) pinocytosis and phagocytosis are pretty much mass transport mechanisms of what are going to be products that the cell utilizes.</p>
<p>Cellulose is the bulk of dietary fiber.</p>
<p>Producers turn radiant energy into chemical energy for their own cellular processes and it pretty much starts the whole food chain. Props to autotrophs!</p>
<p>Always remember: ATP from glycolysis (net 2 gain) are from substrate level phosphorylation (What is it usually, PGAP to PGA? Yeah, I think so.) ATP from Citric Acid Cycle and ETS are from oxidative phosphorylation. (Total 36-38 gain)</p>
<p>Red/blue light is most efficiently converted into chem. energy. Remember why plants are green........</p>
<p>Prokaryotes have no nuclear envelope. That's 7th grade biology. If you show me a prokaryote with a fully developed nuclear envelope, I'll send you the Mona Lisa.</p>
<p>Frozen desert is tundra. Frozen dessert is ice cream.</p>
<p>I'm pretty sure water is most prevalent. That's one of those gay biology questions.</p>
<p>The nondisjunction would occur in anaphase two because the haploid daughter cell would receive two X chromatids and (in this case) get fertilized by another X chromatid from the sperm. When replication occurs, you'd get 3 X chromosomes and that would really suck.</p>
<p>Crossing over allows scientists to determine chromosome maps because the %-rate of crossing over between two alleles is supposedly their map units apart on the chromosome. I don't know if I believe it; I'll have to see for myself.</p>
