Oxidative and Nitrogen Metabolism MCQ Practice (Bio Chem)

Oxidative and Nitrogen Metabolism MCQ Practice (Bio Chem)

Oxidative phosphorylation or electron transport-linked phosphorylation is the metabolic pathway in which cells use enzymes to oxidize nutrients, thereby releasing the chemical energy of molecular oxygen, which is used to produce adenosine triphosphate (ATP). In most eukaryotes, this takes place inside mitochondria. Almost all aerobic organisms carry out oxidative phosphorylation. This pathway is so pervasive because the energy of the double bond of oxygen is so much higher than the energy of the double bond in carbon dioxide or in pairs of single bonds in organic molecules observed in alternative fermentation processes such as anaerobic glycolysis

Nitrogen Metabolism is the polymeric nitrogen containing compounds proteins and nucleic acids that define the major attributes of organism such as function and structure. Operation and mechanism of metabolic pathways is provided by proteins. Genetic information is stored in nucleic acid polymers. Each of the monomer of these macromolecules has an individual metabolic pathway. In addition, the monomeric nucleotides are essential for energy turnover as key intermediates in all metabolic pathways and also as second messenger molecules, often in form of cyclic nucleotides

Amino acids contribute to carbohydrate synthesis via gluconeogenesis, to fat synthesis or energy production via acetyl-CoA, and special nitrogen compounds such as catecholamines (neurotransmitters), thyroid hormones, creatine(-phosphate), the protoporphyrin ring (heme), and contribute to nucleic acid and phospholipid synthesis as nitrogen group donor

These questions will give you basic idea for Examination Preparation and/or interview on Oxidative Phosphorylation and Nitrogen Metabolism.

Please Note:

1. These questions are only for practice and understanding level of knowledge only. It is not necessary that these questions may or may not appear for examinations and/or interview questions

2. In this practice test, because of large amount of questions (around 24 questions) some of questions may have repeated

3. I had to put as 70% pass rate because there may also be wrong answers from my side
