<span>Atherosclerosis is a common cause, because there is a lack of blood flow in the person's body, and this can cause a male to be impotent.
Diabetes is also a common cause because once again it causes less blood flow.
In a younger man, a cause could be anxiety. This is because nervousness and being anxious can lessen blood flow.
If you have choices, I suggest choosing one that has to do with less blood flow happening, which that is the main cause.
I hope that this could possibly help you with your studies, and have an amazing day. If you have any more questions, send me a pm. </span>
Hello!
Meiosis occurs in humans, animals, plants and fungi, and its a sexual type of reproduction. The daughter cells are different, cause the chromosomes are mixed. Mitosis is a asexual type of reproduction and the daughter cells are identical.
hugs!
<h2>Answer:</h2>
The correct answer is option A which is, "Electrons are re-energized to be used in NADPH production".
<h3>Explanation:</h3>
In photosystem II, light energy is used to split water molecules which release electrons.
These electrons then move to photosystem I to reduce NADP to NADPH.
Hence electrons in photosystem II are ultimately used to produce NADPH and option C is the correct statement.
Answer:
a.glycolysis d.acetyl CoA b.citric acid cycle e.electron transport chain
Explanation:
Cellular respiration is set of metabolic processes that occur within the cell in order to produce usable energy (ATP) from the nutrients (food). It can be divided into four main stages:
- Glycolysis-anareobic process in which glucose is broken down and it occurs in the cytoplasm. Products of glycolysis are 2 molecules of pyruvate and 2 molecules of ATP.
- Transition- Pyruvate form the glycolysis is transported into the mitochondria, where it is converted to a molecule Acetyl CoA used for further breakdown
- Citric acid cycle or Krebs cycle- aerobic process that occurs in the mitochondria matrix in which 4 molecules of ATP, and NADH are produced
- Electron transport chain-set of reactions that occur within the cristae of mitochondria. NADH and electrons are passed through electron transport chain to result in the production of ATP (32 ATPs for every glucose).
I think when a traffic light malfunctions you should treat the malfunctioning light as stop sign. There are many reasons for why a stop light will stop working or malfunction. mostly this happens if the electricity goes out or one of the bulbs in the signal dies. Malfunctioning traffic signs may be dangerous and many drivers find them confusing.
