STD 11 - 8. Cell the unit of life — NEET STD 11 Science — Question

$(i)$ The complete combustion of glucose, which produces $O_2$ and $H_2O$ as end products, yields energy most of which is given out as heat.

$(ii)$ The scheme of glycolysis was given by Gustav Embden, Otto Meyerhof and J. Parnas and is often referred to as the $EMP$ pathway.

$(iii)$ In glycolysis, $ATP$ is utilised at $4$ steps.

$(iv)$ In both lactic acid and alcohol fermentation not much energy is released; more than seven percent of the energy in glucose is released and not all of it is trapped as high energy bonds of $ATP.$

$(v)$ For aerobic respiration to take place within the mitochondria, the final product of glycolysis pyruvate is transported from the cytoplasm into the mitochondria.

$R$ : Both develop from same mother cell.

$I.$ DNA being a hydrophilic molecule cannot pass through cell membranes

$II.$ Agrobacteriumtumefaciens delivers a piece of $DNA$ known as $'Z-DNA'$ in the Tiplasmid which transforms normal plant cells into tumour cells to produce chemical against pathogens

$III.$ Retrovirus, adenovirus, papillomavirus are also now used as cloning vectors in animal because of their ability to transform normal cells into cancerous cell.

$IV.$ In genetic engineering, $DNA$ from different sources are cut with the same restriction enzymes so that both $DNA$ fragments have same kind of sticky ends
