Concept of Activation Energy
Concept of Activation Energy - For a reaction to occur, reactant molecules must collide with each other. Only those collisions result in product formation which have energy equal or more than a certain minimum energy. This energy is called the thres..
Concept of Activation Energy
For a reaction to occur, reactant molecules must collide with each other. Only those collisions result in product formation which have energy equal or more than a certain minimum energy. This energy is called the threshold energy. This implies that ther..
Activation energy is high for slow reactions.
Example 11: The rate constants of reaction at 700 K and 760 K are 0.011M - 1 s - 1 and 0.105 M - 1 s - 1 respectively. What are the values of 'A' and 'E..
Active Transport
The transport of materials across the cell membranes with the help of energy is called active transport. Both diffusion and osmosis are passive transport mechanisms, not requiring energy. Active transport helps in the transport of ions across the membranes o..
Active Absorption
Movement of ions from the outer space of the cell to the inner space is generally against the concentration gradient and hence requires energy. This energy is obtained through metabolism either directly or indirectly. Various evidences indicate the active uptake of ion..

Active Transport
It is a process by which certain substances like glucose molecules are transported against the concentration gradient. The carrier proteins in the cell membrane carry out the process. The substance present in the medium binds with the active site on the carrier protein forming a comp..

Energy Transfer and Energy Transformation - Energy is the capacity to do work. All living organisms require energy for carrying on their vital metabolic activities. The primary source of energy for living system is solar radiation. The rad..
Activation of Amino Acids
It is the step in which each of the participating amino acid reacts with ATP to form amino acid AMP complex and pyrophosphate. The reaction is catalyzed by a specific amino acid activating enzyme called aminoacyl-tRNA synthetase in the presence of Mg2+. There is a separate aminoacyl tRNA..

This tutor was excellent. very clear on all of the problems. I would like to have more tutoring from Tutor Vista
Tutor Vista tutor helped me understand and gave me some practices and showed me how to do them.
It was a great pleasure working with this tutor was able to take me through the steps of my math problems which was very helpful because since I don't have lots of experience with math by the tutor doing the steps it helps me understand a great deal. Im so excited that Im finally getting this amazing service. We got so much done. thank you.
This tutoring impressed me a lot! not only did the tutors helped me with currect lessions i needed help with, but they prepared me for future trig lessons to come and very useful imformation - gabriella
