Concept explainers
To explain: The production of compounds, lactate and ethanol during fermentation of soy sauce.
Introduction:
Pyruvate is known as the end product of glycolysis continues in two different fates. In aerobic process it undergoes aerobic respiration, but in anaerobic process it undergoes fermentation. There are two types of fermentation occurs by pyruvate, one is lactic acid fermentation another one is the alcoholic fermentation.
To explain: The reason for preservation of soy sauce from having a strong vinegary taste, oxygen is kept out of the fermentation tank.
Introduction:
In anaerobic respiration, pyruvate released from glycolysis either produces ethanol or lactic acid. If it results into ethanol as a product, it is known as alcoholic fermentation. This process is used commercially to make alcoholic beverages, beers, bread, and other bakery products.

- Help me understand how carbon disulfide leads to toxicity in the brain, using terms like distal axonopathy, neurofilaments, covalent cross-linking, adducts, etc.,...please intuitively explain what is happening and where and the effects of it. For example, I know that CS2 reacts with amide and sulfhydryl groups on proteins, but what proteins exactly and where are they located?arrow_forwardWhat is the standard free energy change (in kJ/mole) of the spontaneous reaction between Oxygen and NADH to form H2O2 and NAD+?arrow_forwardRedox Chemistry: Give standard free energy changes expected for the following reactions:-Succinate -> fumarate (using FAD/FADH2)-Oxaloacetate -> Malate (using NAD/NADH)-NADH --> NAD+ (using FMN/FMNH2)-CoQ --> CoQH2 (using Cytochrome C)arrow_forward

The transporter brings glucose into the cell and sends calcium out of the cell. If blood [calcium] = 2.55mM and intracellular [calcium] = 7uM, blood [glucose] = 5.2mM, and intracellular [glucose] = 40uM, what is the free energy of transport? Assume a membrane potential of 62mV (negative inside).arrow_forward
