Question

After synthesis by the ATP synthase complex ATP can readily diffuse from the mitochondrial matrix and does not require any protein transporters. T/F?

Which of the following statements best describes the consequence of ingesting a compound that stimulates ATP hydrolysis by plasma membrane Na⁺-K⁺ ATPase

A.	The pH gradient across the mitochondria membranes would increase
	B.	The rate of conversion of NADH to NAD+ in the mitochondria would decrease
	C.	Heat production would decrease
	D.	The transfer of electrons to oxygen would increase

Which of the following proteolytic enzymes has the greatest effect on the activity of other proteolytic enzymes involved in digestion?

A.	Trypsin
	B.	Chymotrypsin
	C.	Carboxypeptidase A
	D.	Pepsin
	E.	Aminopeptidase

Answer 1

Ans1- This statement is false .

Since , for the transport , ATP is cotransported with ADP in opposite direction with the help of carrier protein.

Ans 2- For the given condition , fourth option - transfer of electrons to oxygen would increase seems to be best description as a consequence of ATP hydrolysis by plasma membrane Na+k+ ATPase.

Ans 3- Option (A) Trypsin is correct.

Since it is the master enzyme responsible for activation of other pancreatic enzymes except amylase.
