How are cells able to transport large molecules? How are molecules transported across a cell membrane? How did mitochondria and chloroplasts most likely arise? How are proteins packaged and transported within a cell? How do cilia and flagella bend?
Explain how signal molecules binding to a membrane receptor can elicit a cellular response. Explain the role of diffusion (osmosis) and active transport? How would amino acids from the bloodstream move across a cell membrane? a. Diffusion. b. Osmosis. c. Facilitated di...
Describe a distinctive property of water, how it reflects the internal organization of water molecules, and its importance for understanding biological systems. How are some species of fish capable of maintaining the temperature within certain body regions above water temperature? What is the adaptive ...
Similarly, 3D GNNs show strong results for protein representation learning with approaches to make their use computationally feasible for these large molecules [121]. Regarding Graph ML for proteins, I am, of course, also delighted about AlphaFold2 [95], which significantly advanced protein structure...
A family of freshwater algae, within the kingdom Plantae. Members of this family form large macroscopic filaments. Pectin A carbohydrate polymer (a polysaccharide) that is part of the cell wall in walled cells of many organisms, such as algae and plants; pectin crosslinks can play a part in...
What functions do carrier proteins perform in active transport? What types of molecules move by simple diffusion, facilitated diffusion, and active transport? When molecules use facilitated diffusion, what kind of protein will they need to help them move molecules across the membrane? ...
flexible chains of molecules that are the construction equipment of life. Enzymes weld together protein, starch, and DNA chains; push needed molecules through cell membranes; repair and regulate DNA, and do essentially all the building, transport, and disassembly that go on within living things. ...
. There are different ways to do loss minimization (how far in weight space to move at each step, etc.). And then there are questions like how big a “batch” of examples to show to get each successive estimate of the loss one’s trying to minimize. And...
What proteins are responsible for facilitated diffusion of polar molecules? Which of the following proteins carries out active transport? A. glucose symport B. Bacteriorhodopsin C. ABC transporter D. NA-K pump Which large molecule is not normally found in urine? ...
What kinds of molecules cannot pass easily through a cell membrane? What are the major component of cell membranes? What are a few ions that must routinely move across cell membranes? What is the semipermeable membrane in all cells? What are the two major components of cell membranes?
