What is active transport? Give one example of this type of transport.Transporting Molecules Through Selectively Impermeable Membranes:Not all molecules can cross biological membranes via simple diffusion. This may be because they are too large or polar. Such molecules require a channel, in ...
Other types of cell transport that require energy involve vesicles. Vesicles are small sacs that are produced from the cell's Golgi apparatus. They collect waste products which they expel from the cell by fusing with the cell membrane, though they can also be used to collect molecules that are...
What type of transport can move big molecules across the cellular membrane? What does the cell membrane keep out? When molecules use facilitated diffusion, what kind of protein will they need to help them move molecules across the membrane? What is the hydrophobic part of the cell membra...
Use of Energy The main difference between active and passive transport is the use of energy during cell transport of materials. Active transport uses energy and passive transport does not. In active transport, molecules are moving against a concentration gradient (or membrane), meaning the cell mov...

In active transport, molecules are moving against a concentration gradient (or membrane), meaning the cell mov...
Active transport, also known as uphill transport, requires the transport of molecules from a low-concentration region to a high-concentration region. Therefore, active transport must couple to another spontaneous process to transport charged or uncharged substrates against their thermodynamic forces.What...
A renal corpuscle is composed of a tangled cluster called a, which filters fluid. The microscopic functional unit of the kidney is the ___. (a) lobule (b) nephron (c) renal papilla (d) renal column. Which molecules remained inside of the dialysis bag? Epithelia ...
Intracellular Transportation Cells are complex structures with many "moving parts" that need to get from one point to another within the cell in order to accomplish metabolic processes. There are specialized organelles in both plant and animal cells that make up the superhighways of a cell. ...
Glycans are basic molecules in all living organisms. However, they are not well characterized due to the unavailability of specific and high-sensitivity detection reagents. We describe here a method for enzyme-based glycan imaging using glycosyltransferases. Azido-sugars are incorporated into target glyc...
Proteins serve as the machinery for the living cells. What type of molecules are used to produce proteins?Central Dogma:The central dogma of molecular biology encompasses the processes of transcription and translation through which genes are expressed and protein...
