Choose the correct combination of labels for the molecules involved in Calvin cycle.

Options:
A A-RuBP, B-Triose phosphate, C-PGA
B A-PGA, B-RuBP, C-Triose phosphate
C A-PGA, B-Triose phosphate, C-RuBP
D A-RuBP, B-PGA, C-Triose phosphate

The correct answer is:
A-RuBP, B-PGA, C-Triose phosphate

Solution:
A - RuBP
RuBP (Ribulose-1, 5-bisphosphate) accepts atmospheric C O 2 in the presence of the enzyme RuBP carboxylase (RuBisCO) and forms a 6-carbon unstable compound which soon splits into two molecules of a 3-carbon compound called PGA (phosphoglyceric acid)
B - PGA
The phosphoglyceric acid molecules are first phosphorylated by using ATP to produce 1, 3-diphosphoglyceric acid.
C - Some molecules of 3 PGAL are converted into its isomer dihydroxyacetone phosphate (DHAP) in presence of enzyme triose phosphate isomerase.

Topic: Biology, Microbes in Human Welfare, NEET
Choose the correct feature of the muscle fibre given below.

Options:
A Contraction of cells as a unit due to the presence of communication junctions
B Fusiform tissue found only in the heart.
C Muscles have striations and are bundled together in a parallel fashion.
D A sheath of tough connective tissue encloses several bundles of the muscle fibres.

The correct answer is:
Contraction of cells as a unit due to the presence of communication junctions

Solution:
Cardiac muscle tissue is a contractile tissue present only in the heart. Cell junctions fuse the plasma membranes of cardiac muscle cells and make them stick together. Communication junctions (intercalated discs) at some fusion points allow the cells to contract as a unit, i.e., when one cell receives a signal to contract, its neighbours are also stimulated to contract.

Choose the correct match from the following.

Options:
A Giraffes with long necks - Lamarck
B Branching descent - Malthus
C Mutation causes speciation - Darwin
D Inheritable factors influence phenotype - de Vries

The correct answer is:
Giraffes with long necks - Lamarck

Solution:
Even before Darwin, a French naturalist Lamarck had said that evolution of life forms had occurred but driven by use and disuse of organs. He gave the examples of Giraffes who in an attempt to forage leaves on tall trees had to adapt by elongation of their necks. As they passed on this acquired character of elongated neck to succeeding generations, Giraffes, slowly, over the years, came to acquire long necks. Nobody believes this conjecture any more.

Choose the correct match w.r.t. the drug, its source, and its action.

Options:
A

Drug	Source	Action

Morphine	Latex of Papaver somniferum	Depress brain activity and is very effective stimulant

B

Drug	Source	Action

Cocaine	Erythroxylum coca	High levels don't cause hallucinations.

C

Drug	Source	Action

Heroine	Acetylation of morphine	Used to reduce pain

D

Drug	Source	Action

Barbiturates	Derivative of opium	Depressed brain activity and produces feelings of calmness, relaxation and drowsiness

The correct answer is:

Drug	Source	Action

Heroine	Acetylation of morphine	Used to reduce pain

Solution:
The most notorious derivative of morphine is heroin. It is synthesized by acetylation of the two hydroxyl groups of morphine with acetyl chloride, hence its other names, diacetylmorphine or diamorphine. Once heroin enters the brain, it is converted to morphine and binds rapidly to opioid receptors. Abusers typically report feeling a surge of pleasurable sensation—a “rush.” The intensity of the rush is a function of how much drug is taken and how rapidly the drug enters the brain and binds to the opioid receptors. With heroin, the rush is usually accompanied by a warm flushing of the skin, dry mouth, and a heavy feeling in the extremities, which may be accompanied by nausea, vomiting, and severe itching. After the initial effects, users usually will be drowsy for several hours; mental function is clouded; heart function slows, and breathing is also severely slowed, sometimes enough to be life-threatening. Slowed breathing can also lead to coma and permanent brain damage

Choose the CORRECT one for photorespiration that occurs in C3 plants.

Options:
A Photorespiration is common in plants having high CO2 compensation point
B Photorespiration is caused by high CO2 and low O2
C It is not affected by light, temperature
D All of the above

The correct answer is:
Photorespiration is common in plants having high CO2 compensation point

Solution:
Photorespiration is a process in plant metabolism where the enzyme RuBisCO oxygenates RuBP instead of getting carboxylated. This process reduces the efficiency of photosynthesis by 25% in C3 plants. In it, plants use oxygen and release carbon dioxide as by product that making use of it. Photorespiration is generally found to occur in peroxisome.
It more in common in C3 plants as they have higher CO2 compensation point due no net evolution of carbon dioxide gas because the rate of photosynthesis (which consumes carbon dioxide) is equal to the rate of respiration (which evolves carbon dioxide).
In a normal photosynthesis process, there is light reaction and dark reaction. In the light reaction, photophosphorylation occurs to generate ATP which will be utilised in making of glucose. The photophosphorylation process occurs in both cyclic and non-cyclic steps with the involved of the photosystem I and II. Dark reaction or light independent reaction process reduces carbondioxide to glucose using the enzyme RuBisCO.

Choose the correct pair from the following.

Options:
A Polymerases - Break the DNA into fragments
B Nucleases - Separate the two strands of DNA
C Exonucleases - Make cuts at specific positions within DNA
D Ligases - Join the two DNA molecules

The correct answer is:
Ligases - Join the two DNA molecules

Solution:
Ligases: These enzymes catalyze the covalent bonding of two substrates to form a large molecule. They catalyze the joining of C–O, C–S, S–N, P–O, etc., bonds by using the energy of ATP. They are also called molecular glue or stickers.
Example: DNA ligase. Two DNA molecules are joined together by a phosphodiester bond in the presence of DNA ligases. The enzymes cannot be utilised for the blunt ends of the fragments of DNA. The bond nature is covalent because of the involvement of electron exchange.

Choose the correct pair from the following regarding responses to abiotic factors.

Options:
A Aestivation : phytoplankton
B Hibernation : seals
C Dormancy : snails
D Diapause : zooplankton

The correct answer is:
Diapause : zooplankton

Solution:
In higher plants, seeds and some other vegetative reproductive structures serve as means to tide over periods of stress besides helping in dispersal – they germinate to form new plants under favourable moisture and temperature conditions. They do so by reducing their metabolic activity and going into a state of ‘dormancy’. In animals, the organism, if unable to migrate, might avoid the stress by escaping in time. The familiar case of bears going into hibernation during winter is an example of escape in time. Some snails and fish go into aestivation to avoid summer–related problems-heat and dessication. Under unfavourable conditions many zooplankton species in lakes and ponds are known to enter diapause, a stage of suspended development.
