Answer;
-Glycolysis produces pyruvate, ATP, and NADH by oxidizing glucose
Explanation;
-Glycolysis is the first of the main metabolic pathways of cellular respiration to produce energy in the form of ATP. Glucose is cleaved or broken down into two three-carbon sugars of pyruvate through a series of enzymatic reactions.
-Overall, the process of glycolysis produces a net gain of two pyruvate molecules, two ATP molecules, and two NADH molecules for the cell to use for energy. Following the conversion of glucose to pyruvate, the glycolytic pathway is linked to the Krebs Cycle, where further ATP will be produced for the cell’s energy needs.

Answer:
C oil is added to meat to produce amino acid
Answer:
The correct answer will be option-B
Explanation:
The process of transcription transcribes the sequence of the bases of genes present on DNA to mRNA which acts as a messenger molecule for the protein synthesis.
The process of transcription is mediated by the presence of enzymes which includes the main transcription enzyme called RNA polymerase. RNA polymerase attaches nucleotides to RNA strand.
The transcription process initiates in three stages: initiation, elongation and termination.
The initiation process begins when RNA polymerase binds to the promoter nucleotide sequence which is present at the start site or the upstream on DNA towards 5' end.
Thus, Option-B is the correct answer.
C. Endothelial contraction
Explanation:
The primary function of the vascular endothelium is to act as an effective barrier system and controls the diffusion of micro and macromolecules and keep the vascular compartments and interstitial spaces intact.
When this endothelial barrier system fails to function, exudation or leakage of fluid, solutes and proteins from the vasculature takes place leading to accumulation in the interstitial spaces.
Failure of endothelial vasculature like endothelial contraction occurs due to binding with mediators or specific receptors like histamine or leukotrienes or also due to any injury.
When there is an endothelial contraction, the intercellular gaps present in between postcapillary venules widen giving space for the fluid leaked from the vasculature to accumulate.
This exudation of fluids is a factor of an acute inflammatory process. In the above case, the high neutrophil count in the pleural fluid confirms a lung inflammatory process. The neutrophils act as the first line of defence against the inflammation.
