Good Samaritan Laws.
Offer legal protection to people who give reasonable assistance to those who are, or whom they believe to be, injured, ill, in peril, or otherwise incapacitated
Answer:
The answer to the question: The nephron uses counter-current exchange between the Loop of Henle and peritubular capillaries to reabsorb glucose back into the blood as this is why glucose should not be found in the urine:___, is, false.
Explanation:
The process of urine processing as filtrate goes through a nephron´s different portions, is pretty complex, but fascinating. Initially, water, certain substances as glucose, sodium, and others, pass through the glomerulus intoo the PCT (Proximal convoluted tubule) where the initial filtrate is formed. This filtrate will then move through other portions to be added to, and substracted from, on different elements, until finally, at the very end, urine is produced. However, one molecule that is reabsorbed early in this process of filtrate production, is glucose. Glucose should not be usually present in urine, unless there has been a huge consumption of it and transporters in the PCT cannot deal with the amount being filtered, or there is a condition like diabetes mellitus. It is in the PCT that glucose reabsorption is done, together with sodium ions. This is why the answer to the statement is false.
The chronological order of events starting from poisoning should be as follows:
- Ricin enters the victim's body
- Ricin is absorbed into the blood and enters the cells
- Ricin binds to ribosomes in the cytoplasm
- Ricin inactivates 28s rRNA in the large subunits of the ribosomes
- Ribosomes are unable to add new amino acids to polypeptides
- Protein synthesis halts in many tissues
- Multiple organ systems fail
- The victim dies
Ricin is a plant toxin. It is poisonous to mammalian cells as it interferes with the catalytic activity of ribosomes in protein synthesis. It irreversibly binds to the ribosomal subunits and halts the polypeptide synthesis process, leading to cell death.
Note: Your question is incomplete, but probably it includes the following options:
a. Ricin is absorbed into the blood and enters the cells
b. Ricin inactivates 28s rRNA in the large subunits of the ribosomes
c. Ricin binds to ribosomes in the cytoplasm
d. Ricin enters the victim's body
e. Multiple organ systems fail
f. Protein synthesis halts in many tissues
g. The victim dies
h. Ribosomes are unable to add new amino acids to polypeptides
