Q:

What is the role of NADP+ in photosynthesis?

Answer

NADP - Nicotinamide Adenine Dinucleotide Phosphate is one of the carrier molecules that transfers high-energy electrons from chlorophyll to other molecules.


NADP+ is the molecule that accepts the electrons given by water. Its reduction by the protein FNR (Ferredoxin NADP+ reductase) gives NADPH,H+.


 


NADPH,H+ can be used in the Calvin Cycle to reduce 1,3-Biphosphoglycerate (1,3-BPG) into Glyceraldehyde-3-phosphate (G3P), a monosaccharide. It becomes NADP+ again and the cycle keeps repeating as long as the chloroplast receives sufficient and appropriate light.

Q:

A passage is given with five questions following it. Read the passage carefully and select the best answer to each question out of the given four alternatives.

 

The saddest part of life lies not in the act of dying, but in failing to truly live while we are alive. Too many of us play small with our lives, never letting the fullness of our humanity see the light of day. I’ve learned that what really counts in life, in the end, is not how many toys we have collected or how much money we’ve accumulated, but how many of our talents we have liberated and used for a purpose that adds value to this world. What truly matters most are the lives we have touched and the legacy that we have left. Tolstoy put it so well when he wrote: “We live for ourselves only when we live for others.” It took me forty years to discover this simple point of wisdom.

 

Forty long years to discover that success cannot really be pursued. Success ensues and flows into your life as the unintended yet inevitable byproduct of a life spent enriching the lives of other people. When you shift your daily focus from a compulsion to survive towards a lifelong commitment to serve, your existence cannot help but explode into success. I still can’t believe that I had to wait until the “half-time” of my life to figure out that true fulfillment as a human being comes not from achieving those grand gestures that put us on the front pages of the newspapers and business magazines, but instead from those basic and incremental acts of decency that each one of us has the privilege to practice each and every day if we simply make the choice to do so.

 

Mother Teresa, a great leader of human hearts if ever there was one, said it best: “There are no great acts, only small acts done with great love.” I learned this the hard way in my life. Until recently, I had been so busy striving, I had missed out on living. I was so busy chasing life’s big pleasures that I had missed out on the little ones, those micro joys that weave themselves in and out of our lives on a daily basis but often go unnoticed. My days were overscheduled, my mind was overworked and my spirit was underfed.

 

What according to the passage is success?

 

A) Success cannot be pursued. B) Success is an unintended yet inevitable byproduct of a life spent enriching the lives of others..
C) Success is true fulfillment. D) Success is incremental act of decency.
 
Answer & Explanation Answer: B) Success is an unintended yet inevitable byproduct of a life spent enriching the lives of others..
