How do large molecules move across the cell membrane through facilitated diffusion?

Biology
1 answer:
Svetlanka [38]3 years ago
8 0

Answer:

Explanation:

In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers. A concentration gradient exists for these molecules, so they have the potential to diffuse into (or out of) the cell by moving down it.

levacccp [35]

Answer:

explanation below

Explanation:

Leprosy, known as Hansen’s disease, is a chronic infection that is caused by Mycobacterium leprae. This disease damages peripheral nerves and effect areas like skin, yes, muscles and noses. Antibiotics are used to treat the infection between 6 – 12 months. When infected people refuse to follow the treatment schedules given to them by the medical experts, there is usually the development of more antibiotic-resistant M. leprae.  

M. leprae, just like tuberculosis, cell walls contain fatty molecules known as mycolic acids, which make the bacteria less susceptible to antibiotics.  

Researchers have made remarkable progress in developing drugs such as ethionamide, isoxyl, thiolactomycin, and triclosan that are known to inhibit mycolic acid biosynthesis.  

The development of these drugs are part of the tuberculosis drug discovery efforts (in the last one decade) which has been successfully applied to therapeutic targets in the unique mycobacterial wall.  

Since morphology and cell wall of M. leprae does not differ remarkably from that of M. tuberculosis, antibiotic developed to inhibit the biosynthesis of mycolic acids would help to treat leprosy

D - Telophase
Eddi Din [679]

Answer:

A-B-C-D

Explanation:

PROPHASE; 1. chromosomes become thicker

2. nuclear membrane disintegrates

3. centrosome divide to form centrioles

4. centrioles move to the opposite polls of the cell

METAPHASE; 1. chromosomes get arranged at the equator

2. centrioles produce spindle fibre that attach to the middle of the chromosomes

ANAPHASE; 1. shortest stage of mitosis

2. spindles will pull apart each chromosomes to form chromatids

TELLOPHASE; 1.  each chromatid moves to opposite polls of the cell

2. nuclear membrane appears around both of them

3. the centrioles sill stop producing spindles

4. centrosomes will then form again

cytokinesis then divides by the cleavage furrow to form the two daughter cells
