Question

1)Which of these amino acids is most likely to be found in the center of a membrane bilayer in a transmembrane protein?

Lysine

Histidine

Serine

Tyrosine

Valine

2)Consider the following processes associated with the transport of substances across a lipid bilayer:

i) Facilitated diffusion

ii) Passive diffusion

iii) Primary active transport

iv) Secondary active transport

Which of these processes require the inputs of energy in order to occur? Choose from the options below:

i) and ii)

i) and iii)

ii) and iii)

iii) and iv)

ii) and iv)

A.

Lysine

B.

Histidine

C.

Serine

D.

Tyrosine

E.

Valine

Explanation / Answer

1) amino acids is most likely to be found in the center of a membrane bilayer in a transmembrane protein should be non polar so the answer is

Valine

2) active transports need energy.

Primary active

Secondary active
