3 0

Answer and Explanation:

Most young roots have two main regions. An outer cortex and a central cylinder containing the vascular bundles.

The endodermis also referred to as starch sheath. Its cells have a casparian strip which is made up of an impervious waxy deposit on the radial and cross walls. It controls entry of water and dissolved salts into the vascular bundle.

On what basis are enzymes classified and named?
Zielflug [23.3K]

Enzymes are classified and named according to the<u> types of reactions they catalyze.</u>

Explanation:

According to the International Union of Biochemistry and Molecular Biology nomenclature of enzyme classification, enzymes are classified depending upon the reactions they catalyze and how the reaction transforms the substrate and forms new products.

Based on the reactions:

Addition reaction (removal of a water molecule): hydrases or hydrolases like esterases, nucleases etc

Electron transfer reaction: Oxidases and dehydrogenases

Radical transfer reaction: Transglycosidases, transaminases, etc

Splitting or C-C bond formation: Desmolases

Structural or geometrical change: Isomerases

Hydrolysis of phosphate bonds to join molecules: Ligases

Based on the general principle of recommendations, enzymes are suffixed with –ase  depending upon the catalytic reaction and substrate.

Unassembled or misfolded proteins in the RER can be damaging to the physiology of a cell and therefore are transported to the cy
Y_Kistochka [10]

Answer:

The correct answer will be option-C

Explanation:

Endoplasmic reticulum and the Golgi apparatus are the organelles where the post-translational modifications of proteins take place like folding of proteins.

Sometimes few proteins fail to fold properly and are a waste to the cell so has to de degraded. The misfolded proteins move from the endoplasmic reticulum to the cytosol through a process called "Protein dislocation".  

Although the process is not properly misunderstood the protein degradation in the cytosol take place through deglycosylation and proteasomal ubiquitination.

Thus, Option-C is the correct answer.

Why does atp production via oxidative phosphorylation require an intact mitochondrial membrane?
lukranit [14]

Answer:

Production of ATP via oxidative phosphorylation require an intact mitochondrial membrane because of the creation of an electrical potential.

Explanation:

Oxidative phosphorylation is a method, in which energy is converted into ATP by a sequence of protein complexes located inside the mitochondrial inner membrane. Production of ATP through oxidative phosphorylation requires an intact mitochondrial membrane because a change in electrical charge between both sides of the inner mitochondrial membrane results in the creation of an electrical potential. The protons have accumulated on the exterior of the mitochondria, making it positive (H), while the protons have been lost within, making it negative. On each surface of the membrane, a differential or gradient in chemical concentration has been formed. The cell transmits the energy stored in the decreased NADH and FADH via the electrochemical gradient.
