Answer:
Correct answer is c. It is the final electron acceptor in the aerobic respiration.
Explanation:
Oxygen is a substrate of the aerobic respiration, but it is not the only one. Glucose is also a substrate.
Oxygen is used in the cells to be the final electron acceptor, this means that receives the electrons from NADH and FADH2. That is why, when there is no oxygen available for aerobic respiration, the NADH and FADH2 cannot be oxidized and therefore remain in their reduced form. As a consequence, they cannot be re-utilized during different cellular processes that are NAD+ and FAD dependant, such as glycolysis, pyruvate oxidation and cellular respiration. This means that the ATP synthesis stops.
Oxygen itself does not transport any electrones, this are transported by the cytochrome complex in the mitochondrial membrane. But oxygen is key in receiving those electrones, therefore a very important piece of the electron transport across the mitochondria.
Answer:
The answer is- Increased blood glucose, decreased GI peristalsis, and increased heart rate and blood pressure
Explanation:
The sympathetic nervous system (SNS) is a branch of the Autonomic Nervous System (ANS). Sympathetic Division of the ANS responds to threats- to fight or to run away. The stimulation of the sympathetic nervous system causes vasoconstriction of most blood vessels, including those of the digestive tract, skin and the kidneys.
It does the following;
- Increases the rate and strength of contraction of the heart
- Dilates the bronchioles of the lungs
- Decreases movement in the stomach and intestines (decreasing GI peristalsis)
- Increases the breakdown of glycogen and release of glucose from the liver thereby increasing blood glucose
- It dilates the pupil
- increases sweat secretion from the sweat glands
- constricts blood vessels of the skin
- Dilates blood vessel of the skeletal muscle
- Constricts blood vessels of internal organs except the heart and the lungs.
- Relaxes the muscle wall of the urinary bladder
- Stimulates hormone (epinephrine and norepinephrine) secretion from the adrenal medulla
NOTE: GI is Gastrointestinal tract
Answer:
advantages of using a radiation tool can be
