When a protein denatures, which type of bonding is effected?

Biology

GenaCL600 [577]2 years ago

3 0

Answer:

When a protein is denatured, secondary and tertiary structures are altered but the peptide bonds of the primary structure between the amino acids are left intact. Since all structural levels of the protein determine its function, the protein can no longer perform its function once it has been denatured.A protein becomes denatured when its normal shape gets deformed because some of the hydrogen bonds are broken. Weak hydrogen bonds break when too much heat is applied or when they are exposed to an acid (like citric acid from lemon juice).

How does eukaryotic cellular division differ from prokaryotic?

Feliz [49]

Prokaryotic cells are simpler than eukaryotic cells. This is because prokaryotic cells have a single circular chromosome, no nucleus, and few other organelles. Eukaryotic cells have many chromosomes inside a nucleus, and they also have more organelles.

The suprachiasmatic nuclei enable the nervous system to respond to daily light/dark alterations through their stimulation of

timama [110]

Answer:

The suprachiasmatic nuclei enable the nervous system to respond to daily light/dark alterations through their stimulation of melatonin.

Explanation:

Melatonin is a hormone produced naturally by the body. Its function is to regulate the body's circadian cycle. This hormone is stimulated and begins to act by changing between a light environment and a dark environment. This stimulation interacts with the suprachiasmatic nuclei making the nervous system understand this change and luminosity of the environment and respond to the action of melatonin.

The process of phagocytosis involve all of the following except

evablogger [386]

Hello, I figured your question was missing its options so I went online to find them. Here they are:

The process of phagocytosis involves all of the following EXCEPT :

a. adhesion.

b. secretion of cytotoxins.

c. elimination.

d. vesicle fusion.

e. chemotaxis.

Answer:

The correct answer is: b) secretion of cytotoxins.

Explanation:

Phagocytosis is a mechanism performed by cells in which the plasma membrane engulfs a large particle. Phagocytosis is used by cells in the immune system to ingest pathogens like viruses and bacteria.

Phagocytosis consists of many steps:

activation - the phagocytes that were resting are activated in the inflammatory response when a pathogen enters the body.
chemotaxis - this refers to the process in which the phagocyte moves to the pathogen by following the chemical factors released by these germs.
adhesion - the phagocyte attaches to the pathogen.
ingestion /vesicle fusion - the phagocyte sends pseudopods to engulf the pathogen, and places it in a phagosome, which is an endocytic vesicle. The phagosome and the phagocyte will fuse so the pathogen gets inside.
elimination - the pathogen is destroyed in the phagocyte by the lysosomes present in it.

The secretion of cytotoxins is not a part of the phagocytosis, and is a process exclusive to T cells (leukocytes that lack the ability to phagocyte).
