Why does active transport require an input of energy (needs to include equilibrium and the laws of thermodynamics in the answer) Explain the difference between primary and secondary active transport, provide examples of each.
Ans.) In active transport, the molecule is transported from a region of lower solute concentration to region of higher concentration to attain a equillibrium. Whereas according to law of thermodynamics the uphill process requires input of energy as it is non-feasible on its own, because of higher concentration on another side the molecule entering faces hindrence. So energy is needed to counter this hindrence.
In primary active transport, the molecule is transported from low concentration to higher concentration directly using energy.
However, in secondary transport, the molecules are transported uphill to concentration moves along the another molecule which is moving down its concentration gradient, however energy is used to transport the second molecule back to the region of its high concentration.

A. a protein that facilitates a reaction B. a protein that supplies water for hydrolysis reactions C. a protein that absorbs water during dehydration reactions The First Law of Thermodynamics states: A. energy can be changed from one form...
What is the difference between passive and active transport? Provide an example of a transport protein involved in the passive transport of K+, and one protein involved in the active transport of K+ across the plasma membrane and explain the direction of the flow of K+ in each case (from inside the cell to the outside, or from the outside of the cell to the inside). Also explain for each of your examples if the transport is uniport, symport, or...

What inhibits them and what stages or reactions are these enzymes involved in? What type of inhibition and/or feedback is involved in each example? 6. Explain the difference between secondary and primary active transport. Give a real-world example where each one is used. Describe these examples in detail.
In the lower bound proof for sorting, why does a sorted input require fewer comparisons than an unsorted one? (Hint: think about how much you 'learn' from each comparison in both of those cases.)[2 points]
