high-energy electrons
Both contain the useful metal titanium. Titanium can be refined from them profitably.
Diploid, it is somatic cell therefore will contain 46 chromosomes (23pairs) in humans
Loss of electrons causes NADH to become NAD+. This cycle of oxidation reduction helps generate ATP in cell respiration.
humans cells contain dna, but the cell of archaea do not
A cell is the smallest living thing in your body. It contains a cell membrane, organelles, a nucleus, mitochondria, ribosomes, endoplasmic reticulum, Golgi apparatus, chloroplasts, vacuoles, and cytoplasm.
NADH
NADH
One reason is that the lysosomes contain very powerful enzymes which could destroy the cell (or parts of it) if they were not isolated from the rest of the cell.
NADH
It is stored in NADH and FADH2
The fermentation pathway itself does not generate NADH itself. In fact NAD+ builds up. Glycolysis uses the NADH when oxidating carbon substrates and fermentation is used to regenerate the NAD+ and thus the cycle continues. If fermentation did not exist, NADH would build up and the cell would not be able to oxidize carbon anymore. The cell would die. In the case of respiration (aerobic or anaerobic) the cell will replenish its NAD+ pool the electron transport chain (oxidative phosphorylation). This generates even more potential to make ATP by pumping protons out of the cell using the energy generated from NADH -> NAD via NADH dehydrogenase. This gradient can be utilized by allowing the protons to flow back into the cell through ATPase, generating ATP. The utilization of NADH to pump protons out of the cell is the sole reason why respiration generates 36-38 ATP while fermentation generates 2 ATP per glucose. After much rambling, the point to take home is that the main job of fermentation in the cell is the replenish the NAD+ pool so that glycolysis can continue which drives biosynthesis.
The Krebs cycle produces high-energy molecules, such as NADH and FADH2, which carry electrons to the electron transport chain for ATP production. It also generates carbon dioxide as a waste product. Overall, the Krebs cycle is essential for generating energy in the form of ATP for the cell's metabolic processes.
NADH levels would increase in the cell due to the build-up of acetyl CoA, as it cannot be converted to citrate. This is because the enzyme responsible for converting acetyl CoA to citrate is inhibited, leading to a block in the tricarboxylic acid (TCA) cycle and subsequent accumulation of NADH.
NADH (nicotinamide adenine dinucleotide) is a coenzyme found in cells that plays a crucial role in the process of cellular respiration. It serves as an electron carrier, helping to transfer electrons from one molecule to another during the production of ATP, the cell's main energy source. NADH is produced during the breakdown of sugars and fats in the cell.
NADH is a coenzyme that carries electrons from glucose molecules through the electron transport chain in the mitochondria. These electrons are used to generate ATP, the cell's primary energy source, through a process called oxidative phosphorylation.
Low NAD+ and high NADH can lead to a decrease in the cell's ability to produce energy through cellular respiration. This imbalance can disrupt metabolic processes and affect the redox balance in the cell, leading to oxidative stress and potential cell damage. It can also impact other essential cellular processes that rely on NAD+/NADH balance, such as DNA repair and gene expression regulation.
