Lec 13

Question 1

Mitochondrion makes

Answer 1

ATP

Question 2

Mitochondrion has

Answer 2

Outer and inner layer

Phospholipids

Mitochondrial DNA

Proteins

Question 3

Mitochondrial DNA

Answer 3

Nucleotides imported from cytosol

Question 4

ORI in MT

Answer 4

Two replication forks connect two ORIs together

Question 5

Most proteins in the MT

Answer 5

Made by free ribosomes in the cytosol

Imported by translocase proteins and puts them into proper membrane or space

Question 6

Translocase in the outer membrane is called

Answer 6

TOMs

Question 7

Translocase in the inner membrane is called

Answer 7

TIMs

Question 8

TOM/TIM signal

Answer 8

Protein signaling to import into mitochondria

Question 9

MT reproduction

Answer 9

ER wraps around MT and pinches it, dividing it

Question 10

Heme group

Answer 10

Little organic circle found in proteins like hemoglobin that transports oxygen

Question 11

Heme synthesis

Answer 11

Iron exits lysosomes through DMT1 membrane transport proteins

Question 12

Iron import + Heme export

Answer 12

Porin proteins in outer membrane move iron in

To get past inner membrane, a specific transporter is used

Iron is used to make hemes

A specific transporter allows the hemes to leave the inner membrane and the porin allows it to leave the out membrane

Question 13

MT triggers

Answer 13

apoptosis

Cell destruction

Question 14

Retina specific function of MT

Answer 14

Mutations in mitochondrial DNA can cause blindness
