A common reducing agent used to couple chemical reactions in cells is?
NADH (nicotinamide adenine dinucleotide) is a common reducing agent used to couple chemical reactions in cells. NADH donates electrons and protons to other molecules, enabling various metabolic pathways to proceed.
Are disaccharides considered reducing sugars?
Yes, disaccharides are considered reducing sugars because they have free aldehyde or ketone groups that can reduce other substances.
Why are lactose and maltose considered reducing sugars, while sucrose is not?
Lactose and maltose are considered reducing sugars because they have a free aldehyde or ketone group that can reduce other substances. Sucrose, on the other hand, does not have a free aldehyde or ketone group, so it is not considered a reducing sugar.
Are substance considered reducing fehlings test also the substance reducing in benedicts test?
yes.
What is the A340 value for NADH?
The millimolar extinction coefficient of NADH at 340 nm is approximately 6.22 mM-1 cm-1.
What is the goal of the ETC?
To create reducing power (NADH) leading to ATP synthesis
What does NADH and FADH2 power?
NADH and FADH2 are electron carriers that power the electron transport chain in cellular respiration. This process generates ATP, the cell's main energy currency, by transferring electrons from NADH and FADH2 to molecular oxygen.

Why is reducing power considered as form of energy?
Reducing power is considered a form of energy because it represents the ability of a substance to donate electrons in a chemical reaction, which can result in the release of energy as the electrons are transferred. This transfer of electrons allows for the generation of a flow of electrical current, which can be harnessed to perform work or power devices.
At the end of the citric acid cycle most of the energy remaining from the original glucose is stored in where?
Most of the energy remaining from the original glucose is stored in the form of high-energy electrons in NADH and FADH2 molecules. These molecules will then proceed to the electron transport chain, where they will be used to generate ATP through oxidative phosphorylation.
How does the process of fermentation allow the survival of yeast?
Fermentation allows yeast to survive in an anaerobic environment without suffering the NAD+/NADH imbalance and lactate acidosis associated with regular anaerobic respiration. Excess NADH is shunted to produce ethanol from pyruvate, reducing NADH levels, replenishing NAD+ levels, and preventing the formation of acidic lactic acid.
Is NADH an electron acceptor?
Not exactly. It is true that NAD is formed during electron transport chain, however, it's not a direct product. NADH is an electron carrier that dumps its electron to the electron transport chain, which oxidizes it into NAD. NAD then goes back to become reduced by glycolysis or citric acid cycle.
NADH is produced during?
NADH is produced during glycolysis, the citric acid cycle, and the electron transport chain in cellular respiration. It is a reducing agent that carries high-energy electrons to the electron transport chain to produce ATP.
What is the role of enzyme complex in the electron transport chain?
A. Transfer electrons to NAD+ B. Power Krebs cycle C. Receive electrons from NADH D. Produce ATP from sugar
What is the product from the Krebs cycle?
NADH
Where does the conversion of pyruvic acid to lactic acid takes place?
The conversion of pyruvic acid to lactic acid occurs in the cytoplasm of the cell. This process, known as lactic acid fermentation, is a way for cells to regenerate NAD+ from NADH in the absence of oxygen.
What is the ATP conversion for one NADH?
One NADH molecule generates approximately 2.5 to 3 ATP through oxidative phosphorylation in the mitochondria.
