Enzyme synthesis cannot be a function performed by a membrane protein.
<u>Explanation:</u>
Membrane protein is found on the lipid bilayer that surrounds the cell. Enzymes are the globular structures of proteins which are made by the translation of the specific m-RNA in the cytosol of the cell and not by the membrane proteins. While a membrane protein can be used as a pump to transport ions across the membrane, it can be used for cell-cell or cell-matrix adhesion and as a hormone binding protein.
Answer: adult tissues
Explanation: Adult stem cells. These stem cells are found in small numbers in most adult tissues, such as bone marrow or fat. Compared with embryonic stem cells, adult stem cells have a more limited ability to give rise to various cells of the body.
Answer:
Kidneys : helps in forming urine
Ureter : They are connected to kidney and by peristaltic action transports urine from kidneys to bladder .
Urinary bladder : It is an hollow sac that holds the urine .
Urethra : transports urine from the bladder to outside of the body .
Explanation:
The human excretory system consists of : Kidney ,ureter ,urinary bladder and urethra .The figure is shown below .
Now , as far as functions are concerned we have :
Kidneys : They have excretory units called nephrons that further consist of :
- Bowman's capsule
- PCT (Proximal convoluted tubule )
- DCT (Distal convoluted tubule)
- CT (collecting tubule )
In nephrons urine is formed and via ureter it is transported to a hollow sac like structure called urinary bladder .
This bladder has muscles that cant remain contracted up to longer period )and then voluntary and involuntary it is excreted through urethra .
The process of passing urine is called Micturition .
