- Or. Foyez Samar The volume enclosed by the plasma membrane of plant cells is often much larger the c corresponding volume in animal cells. The most regsengble explanation for this observation Is that A) plant cells are capable of having a much higher surface-to-volume ratio than animal cells. B) plant cells have a much more highly convoluted (folded) plasma membrane than animal cens. C) plant cells contain a large vacuole that reduces the volume of the cytoplasm. D) animal cells are more spherical, whereas plant cells are elongated. 12 A uDefine biomineralizationSignal propagates inside cells via • Feedback • Phosphorylation cascade • “Second messenger” • Describe the words above.

- Give some Examples of membrane proteindiversity ?Hello, May I get help with this question? I do not understand it, steps leading to the correct answer would be helpful. Question: Bruce B. was deep in the woods and drank something he probably shouldn't have (why do people keep doing this?!?!). He's with a medical doctor and trained outdoorsman who tells him that, if he doesn't get treatment immediately, the toxins in the fluid will start to lock tropinin in place just in the sarcomeres in his digestive system. He asks you, an actual physiologist, what this means and what parts of digestion, secretion, absorption, and motility will be affected. Which of the following will be MOST affected...(see image)Define quorum sensing and provide examples of cellular processes regulated by quorum sensing
- 121 11) The table below compares and contrasts carrier protein pumps with clathrin-dependent receptor-mediated endocytosis. Fill in the empty spaces of the table with the appropriate answer Clathrin- Carrier protein dependent receptor mediated endocytosis pump Involvement of multiple types of proteins? (Yes/No) Involvement of ATP? (Yes/No) Involvement of dynamin? (Yes/No) Membrane proteins involved are specific for only a small number of different types of substances? (Yes / No) Possible direction of movement of transported molecules (Into cell/Out of cell/Both) Requires formation of a vesicle? (Yes/No)My research goal is to identify the molecular mechanisms and factors which affect the regulatory systemA. Fill in the blank: The motor protein responsible for transporting vesicles to the plasma membrane is named ____________. (spelling matters!) B. Specific inhibitors of dyneins have yet to be discovered. When they are discovered, how would they most likely affect cells? Reduce retrograde transport of endosomes Decrease pseudopod formation in amoeboid cells Increase cell size Decrease contraction of skeletal muscle
