Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R
Assertion A : In Gas-Liquid Chromatography (GLC) the Fatty Acid Methyl Esters (FAMEs) with long fatty acyl chains come out first from the column.
Reason R : Increased chain length of fatty acids leads to lower volatility and their increased retention on the GLC column.
In light of the above statements, choose the correct answer from the options given below

A. Glycerol-3-P dehydrogenase
B. Glycerol-3-phosphate acyltransferase
C. Lysophosphatidic acid acyltransferase
D. Phosphatidic acid phosphatase
E. Diacylglycerol acyltransferase
Choose the correct sequence of the action of aforementioned enzymes of the "Kennedy pathway" in the triacylglycerol biosynthesis.
Components of the mitochondrial Electron Transport Chain (ETC):
A. NADH-Coenzyme Q oxidoreductase
B. Cytochrome \(bc_1\) complex
C. Ubiquinone
D. Cytochrome C
E. Cytochrome C Oxidase
Choose the correct sequence of electron transfer through the aforementioned components of the mitochondrial ETC
Six enzyme classes have been recognized and approved by International Union of Biochemistry since 1961. In 2018, which one of the following group of enzymes has been added as the seventh class, with Enzyme Commission number 7 (EC 7), by the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology (NC-IUBMB)?
Enzymes involved in the complete oxidation and utilization of odd-chain fatty acids:
A. Propionyl CoA carboxylase
B. Thiolase
C. Fatty acyl CoA synthetase
D. Methylmalonyl CoA mutase
E. Methylmalonyl CoA racemase
Choose the correct sequence in which aforementioned enzymes act for the purpose of oxidation and utilization of odd-chain fatty acids as a source of energy.
Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R
Assertion A : The uncompetitive inhibitors bind only to the enzyme-substrate (ES) complex and not to the free enzyme.
Reason R : Binding of the substrate to the enzyme causes a change in its conformation, which reveals the inhibitor-binding site.
In light of the above statements, choose the correct answer from the options given below
The mitochondria play a direct role in which of the following subtype(s) of $\text{C}_4$ photosynthesis?}
Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R
Assertion A : The presence of thick and fleshy water-storing leaves or stems in CAM plants enhances their photosynthetic efficiency.
Reason R : The photosynthetic rates in CAM plants are limited by their vacuolar storage capacity, as malate synthesized at night through carboxylation of PEP has to be stored in the large central vacuole until the daytime.
In light of the above statements, choose the correct answer from the options given below
