Flashcards in dec1pt2 Deck (20):
1

taste receptor sodium channel candidate

amiloride sensitive sodium channel

2

taste receptor proton channel candidate

complex formed by PKD113 and TRP

3

umami,sweet, and bitter use this type of mechanism

GPCR

4

receptor type for bitter

T2

5

receptor type for umami and sweet

T1

6

Types of T1

T1R1, T1R2, T1R3

7

T1 receptors form

heterodimers

8

taste receptor cells either generate AP or

rely on calcium influx through TRPM5 for NT release without AP

9

few types of

sweet receptors, just need to know energy source

10

same G protein

umami and sweet

11

bitter G protein

gustducin

12

cells expressing T1R2 do not express

T1R1

13

knockout T1R1 and firing rate of what is abolished

umami gustatory nerves

14

knockout T1R3 abolishes

umami and sweet

15

abolishes sweet

knockout T1R2

16

no evidence these form heterodimers

T1R1 and T1R2

17

if you put a sweet receptor in a bitter taste cell animals will

avoid sweet

18

animal experiemnt supports

labled line theory

19

miarculin works by

binding T1R2T1R3 complex and activating it at pH change

20

T receptors parcing
