The following points highlight the top three classical theories of oxidative phosphorylation. The theories are: 1. The Chemical Coupling Theory 2. The Conformational Coupling Theory and 3. The Chemiosmotic Coupling Theory. Classical Theory # 1. The Chemical Coupling Theory: This theory was first proposed by Slater in 1953 and is based on the principles of substrate-level phosphorylation as illustrated by [...]
The below mentioned article provides a study note on the respiratory quotient. The ratio of the volume of CO2 released to the volume of O2 taken in respiration is called as respiratory quotient and is denoted as R.Q. R.Q. = Vol. of CO2 /Vol. of O2 Value of Respiratory Quotient: The value of R.Q. depends upon the nature of the [...]
Let us make an in-depth study of the pentose phosphate pathway. After reading this article you will learn about 1. Reactions of Pentose Phosphate Pathway and 2. Significance of Pentose-Phosphate-Pathway. Pentose Phosphate Pathway (Warburg-Dicken's Pathway): It involves the oxidation of Glucose-6-Phosphate to 6-Phosphogluconic acid which in turn is converted into pentose phosphates. In this pathway glucose-6-phosphate is directly oxidised without [...]
