When someone sheds tears, they are expelled from cells through a mechanism known as endocytosis.
Response:
The question is lacking certain details, and I have included the complete question in the request for further information section. Since this inquiry pertains to outlining a process, I have outlined steps for enhanced comprehension.
Clarification:
INITIAL STEP 1
Adding valinomycin
STEP 2
Valinomycin binds with K+ ion
STEP 3
The electrical potential across the mitochondrial membrane diminishes
STEP 4
ATP hydrolysis rate escalates
STEP 5
ATP synthesis rate declines
STEP 6
The pH difference across the mitochondrial membrane surges
STEP 7
The electrical potential across the mitochondrial membrane lessens
STEP 8
The valinomycin-K+ complex can now move into the mitochondrial matrix
STEP 9
The valinomycin-K complex transfers K+ ion out of the mitochondrial matrix
STEP 10
Electron transfer and O2 consumption rates increase
FINAL STEP
Generation of heat
