Explanation:
<u>anaerobic process that restores NAD+ supply
</u>
<u></u>
Within cells, aerobic respiration may not occur due to several factors:
- - a lack of inorganic, final electron acceptors
- -incomplete or lack of a complete electron transport system
- -missing genes for enzymes within the Kreb's cycle
Thus, they utilize other means for the generation of energy in the form of ATP and to replenish NAD+ an oxidized form of NADH, the main electron carrier in glycolysis. Pyruvate is produced in the cytoplasm via glycolysis- it is also used as an electron acceptor in a process called fermentation.
Further Explanation:
overall: C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP
In all eukaryotic cells mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced. Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate( through the process of glycolysis in the cytoplasm).
Oxidative phosphorylation describes a process in which the NADH and FADH2 made in previous steps of respiration process give up electrons in the electron transport chain these are converted it to their previous forms, NADH+ and FAD. Electrons continue to move down the chain the energy they release is used in pumping protons out of the matrix of the mitochondria.
This forms a gradient where there is a differential in the number of protons on either side of the membrane the protons flow or re-enter the matrix through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP. At the end of the electron transport, three molecules of oxygen accept electrons and protons to form molecules of water...
- Glycolysis: occurs in the cytoplasm 2 molecules of ATP are used to cleave glucose into 2 pyruvates, 4 ATP and 2 electron carrying NADH molecules. (2 ATP are utilized for a net ATP of 2)
- The Citric acid or Kreb's cycle: in the mitochondrial matrix- 6 molecules of CO2 are produced by combining oxygen and the carbon within pyruvate, 2 ATP oxygen molecules, 8 NADH and 2 FADH2.
- The electron transport chain, ETC: in the inner mitochondrial membrane, 34 ATP, electrons combine with H+ split from 10 NADH, 4 FADH2, renewing the number of electron acceptors and 3 oxygen; this forms 6 H2O, 10 NAD+, 4 FAD.

Answer: Oviduct
Explanation:
The Oviduct, which is also known as Fallopian tube is a long narrow tube with funnel shaped opening which receives oocytes released by the ovary.
Usually, contractions of the muscular walls of the oviduct pushes the ovulated oocytes down the narrow tube where sperm travels through and fertilizes the oocytes to form zygote, which then is implanted in the uterus.
So, Oviduct is the answer
Answer:
The correct answer to the question: Which of the folowing structures would be considered an accessory organ to the digestive system and NOT part of the alimentary canal?, would be: A: Pancreas.
Explanation:
The accesory organs to the digestive systems are defined as organs that in some part play a role in the entire process of digestion of food, but are not directly a part of the digestive tract itself. As such, the pancreas, though resposible for secreting components that are essential to the process of absorption of nutrients, and management of them, is not part of the digestive system and fufills tasks outside of the purpose of the digestive system, which is, to manage the digestion, absorption and excretion of nutrients and foodstuffs.
Mainly there is cell wall at the outer of prokaryotes ! but not have cell wall as PPLO or mycoplasma don't have cell wall !
<span>Gel electrophoresis is a technique that allows the DNA fragments to separate according to length.
Hope this helps!
