- Question
What is the role of NADP+ in photosynthesis?
- Correct 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

Correct Answer: Developing a habit of wearing your lifejacket or PFD at all times also reduces the chance that you will drown should you find yourself in the water unexpectedly
Correct Answer: All of the above
Explanation:
Glycolysis involves the breaking down of a sugar into more manageable compounds in order to produce energy.
The net end products of glycolysis are two Pyruvate, two NADH, and two ATP.
Correct Answer: Humidity
Explanation:
The amount of water vapor in the air is called Humidity. The amount of water vapor that air acn hold depends on the temperature of the air. The amount of water vapor in the air as compared with the amount of water that the air could hold is called Relative humidity.
Correct Answer: decreases
Explanation:
When water is cooled from 4°C to 0°C, its density decreases.
When water cools from 4°C to 0°C, ice crystals begin to form because the water is approaching its freezing point. When water freezes, the water molecules form a lattice that increases the volume. As a result, the density decreases. This is why ice will float on top of water; ice has a lower density than the water.
Correct Answer: J. E. Purkinje
Correct Answer: TRUE
Explanation:
Exercise can boost your memory and thinking skills by improvising alertness, attention and motivation.
Correct Answer: PET & MRI
Correct Answer: Pest infestation is nothing but the presence of large number of pests at a place, typically so as to cause damage or disease Climatic conditions affect a considerable number of pests Some are more active during warmer periods than others As these summer insects invade your home, they're likely in search of food, water, shelter, or have encountered an entrance To pest-proof your home this summer, it's best to remove their 'WHY? or reason for entering your home * Keep your place clean and dry Make sure there is no food laying about * Removing food residue - food is a common attraction to a number of different pests * Regular disinfection of the surfaces
Correct Answer: All of the above
Explanation:
Here all the options given are important functions of Earth's atmosphere.
Correct Answer: Calcareous rock
Explanation:
