When the circular muscles contract, the earthworm stretches, becoming longer and thinner. The earthworm uses its setae to anchor the front of its body in the soil. Now the longitudinal muscles contract and the earthworm becomes shorter and wider or it bends from one side to the other, pulling the body forward.
Answer: C. Ii & III are correct
II. reduced intracellular ATP.
III. apoptosis or necrosis.
Explanation:
Cytochrome c oxidase controls the last step of food oxidation. Cytochrome c oxidase is an enzyme responsible for electron transfer in the electron transport chain (ETC), it inhibit in slowing down or stopping the ETC.
Consequently, ATP production would be gradually reduced, as the ETC is responsible for the majority of ATP production. This shows option II is correct.
The question starts by stating that cyanide is highly toxic, so this match up with the fact that a large dose would also cause cell death (apoptosis or necrosis). Therefore, option III is also accurate.
Option I: Inhibiting the ETC is consequential as it reduces oxygen demand because electrons would not flow to oxygen, the final electron acceptor.
Answer:
Proteins and phospholipids make up most of the membrane structure. The phospholipids make the basic bag, while the proteins are found around the holes and help move molecules in and out of the cell.
The question is incomplete as the background of the case and symptoms of Jarod is not provided, however, the missing data required for the question is as follows:
Jared was investigating a drug cartel and ate a meal with one of the suspects. After the meal, he had trouble breathing and felt weak and dizzy. Jared may have been poisoned. He is being taken to the CIA hospital for treatment. You are a medical toxologist working for the CIA. It is your job to find out what poison was given to Jared and try to save his life. Patient: Jared Sondheim Age: 32 Occupation: CIA Agent Symptoms: Muscle Weakness Shortness of Breath Dizziness. Jared has arrived at the hospital! It is your job to find out what toxin was used to poison Jared. You can then give him the correct antidote to save Jared's life.
Answer:
Poisning by 2-deoxyglucose syops the glycolysis process which leads to cardiovascular and respiratory symptoms. Due to property of inhibiting the enzyme reqquired for glycolysis, glucokinase. So, there is no ATP production takes place.
Arsenic poisoning inhibits the second stae of cellular respiration, the Krebs cycle which leads to pyruvate accumalation. The symptoms associated with arsenic are diarrhea, sking tone, abdomunal pain, and muscle cramps.
Oligomycin is used as an antibiotic to inhibit proton ATPase present in mitochondria membrane which blocks ATP formation. Watery eyes, cough, congestion in chest and nose are sysmptopms of oligomycin poisining.
The symptoms cyanide poisoning are dizziness, short breath, nd muscle weakness which matches with the symptoms of jarod.
