11What is Thiamin's role in the body?
- AInvolved in energy production in the Electron Transport Chain (ETC), Citric Acid Cycle and also the catabolism of Fatty Acids.
- BInvolved in oxidation-reduction reactions to produce energy (ETC, Citric Acid Cycle, Glycolysis, Cori Cycle and Alcohol metabolism.
- CIt's primarily involved in the generation of energy from Carbohydrates as well as RNA and DNA production and nerve function.
- DIs part of Coenzyme A and is essential for the metabolism of Carbohydrates, Fats and Proteins.
12What is Riboflavin's role in the body?
- AIs part of Coenzyme A and is essential for the metabolism of Carbohydrates, Fats and Proteins.
- BInvolved in the metabolism of Carbohydrates, Fats and Proteins via carboxylase reactions (the addition of CO2)
- Cimportant for Amino Acid and Carbohydrate metabolism via glycogen breakdown, in both transamination (for AA synthesis) and deamination reactions, aids in the synthesis of haemoglobin, niacin synthesis from tryptophan and the synthesis of neurotransmitters (serotonin, dopamine, histamine and GABA).
- DInvolved in energy production in the Electron Transport Chain (ETC), Citric Acid Cycle and also the catabolism of Fatty Acids.
13What is Niacin's role in the body?
- AInvolved in DNA synthesis (the transfer of single carbon units, synthesis of thymidylate (dTMP)) needed for DNA, also part of homocysteine metabolism and neurotransmitter formation. Closely linked to B12
- BInvolved in oxidation-reduction reactions to produce energy (ETC, Citric Acid Cycle, Glycolysis, Cori Cycle and Alcohol metabolism.
- CIt's primarily involved in the generation of energy from Carbohydrates as well as RNA and DNA production and nerve function
- DInvolved in energy production in the Electron Transport Chain (ETC), Citric Acid Cycle and also the catabolism of Fatty Acids.
14What is Biotin's role in the body?
- AInvolved in the metabolism of Carbohydrates, Fats and Proteins via carboxylase reactions (the addition of CO2)
- BIs part of Coenzyme A and is essential for the metabolism of Carbohydrates, Fats and Proteins.
- Cimportant for Amino Acid and Carbohydrate metabolism via glycogen breakdown, in both transamination (for AA synthesis) and deamination reactions, aids in the synthesis of haemoglobin, niacin synthesis from tryptophan and the synthesis of neurotransmitters (serotonin, dopamine, histamine and GABA).
- DInvolved in oxidation-reduction reactions to produce energy (ETC, Citric Acid Cycle, Glycolysis, Cori Cycle and Alcohol metabolism.
15What is Pantothenic Acid's role in the body?
- AInvolved in oxidation-reduction reactions to produce energy (ETC, Citric Acid Cycle, Glycolysis, Cori Cycle and Alcohol metabolism.
- BIs part of Coenzyme A and is essential for the metabolism of Carbohydrates, Fats and Proteins.
- CInvolved in DNA synthesis (the transfer of single carbon units, synthesis of thymidylate (dTMP)) needed for DNA, also part of homocysteine metabolism and neurotransmitter formation. Closely linked to B12
- DInvolved in folate metabolism by removing methyl groups from THF, involved in maintenance of myelin sheaths and the metabolism of short chain fatty acids so they can enter the Citric Acid Cycle.
16What is B6's role in the body?
- Aimportant for Amino Acid and Carbohydrate metabolism via glycogen breakdown, in both transamination (for AA synthesis) and deamination reactions, aids in the synthesis of haemoglobin, niacin synthesis from tryptophan and the synthesis of neurotransmitters (serotonin, dopamine, histamine and GABA).
- BIt's primarily involved in the generation of energy from Carbohydrates as well as RNA and DNA production and nerve function
- CIs an antioxidant, increases iron absorption, aids in the synthesis of carnitine, tryptophan (then to serotonin), thyroxine, corticosteroids, aldosterone and cholesterol (then to bile acids), also aids in immune functions and collagen synthesis.
- DInvolved in the metabolism of Carbohydrates, Fats and Proteins via carboxylase reactions (the addition of CO2)
17An Oxidation-Reduction reaction (Redox reaction) is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron. Redox reactions are common and vital to some of the basic functions of life, including photosynthesis, respiration, combustion, and corrosion or rusting.

20What are the symptoms of Wet Beriberi?
- AOedema, enlarged heart, and heart failure as a result of the accumulation of pyruvate and lactate which are not able to be metabolised which equals vasodilation and fatigue.

- DNystagmus (involuntary eye movement, double vision), Ataxia (staggering, poor muscle coordination, mental confusion "drunken stupor").
21Dry Beriberi is generally seen in physically active individuals due to their increased requirements for Glycolysis
