Answer:
The proton gradient produced by proton pumping during the electron transport chain is used to synthesize ATP. Protons flow down their concentration gradient into the matrix through the membrane protein ATP synthase, causing it to spin (like a water wheel) and catalyze conversion of ADP to ATP.

Explanation:
The best answer is A.
As soon as the blood vessel wall is broken or damaged, a series of reactions activate platelets so that they stick to the site of injury. The platelets are able to hold to the blood vessel wall by means of a protein substance called von Willebrand's factor.
Collagen and thrombin then act at the site of injury and induce platelets to clump or stick together, forming a mesh that plugs the broken part. Special clotting protein help sequester more platelets to the plug which finally becomes a blood clot.

Question: Susan was bitten by an Anopheles mosquito and tested positive for malaria. What type of pathogen has caused this infection
a. Bacterium
b. Protozoan
c. Prion
d. Virus
Answer:
b. Protozoan
Explanation:
Plasmodium is the causative agent of malaria and is carried by female Anopheles mosquito. The parasite enters the bloodstream when the female Anopheles mosquito bites. Plasmodium is a parasitic protozoan and belongs to the kingdom Protista. Protozoans are unicellular eukaryotes. They are heterotrophic organisms and derive their nutrition from parasitism or predation. Plasmodium is a sporozoan since its spore life stage of the life cycle is infectious.
