synthesis of proteins. And since the synthesis of proteins is necessary for maintenance of the cell, most of the processess will be stopped afterwards.

If a toxin such as a bacterial toxin destroys ribosomes what cellular activity will be affected first?
protein syntheisis b/c DNA----> RNA----> proteins from ribosomes
What is the inhibitor of 80s ribosomes?
80S ribosomes are inhibited by a number of agents. Some are differential inhibitors 80S ribosomes (found in eukaryotic cells) and 70S Ribosomes (found in prokaryotic cells and mitochondria. Among them are: Cycloheximide (CAS 66-81-9): Inhibits peptidyl transferase activity of the 80S ribosomes, with comparatively little effect on 70S ribosomal function Ricin (CAS 9009-86-3) is a very powerful inhibitor of protein synthesis in 80S ribosomes, and it's reported to be irreversible. Ricin is extremely toxic and is considered a weapon-making material. α-sarcin (CAS 86243-64-3) cleaves a ribosomal RNA on 80S ribosomes. Other inhibitors of 80S ribosomes include Shiga-like toxin Stx2; Abrin (CAS 1393-62-0).
What the cell nucleus functions?
AS for as i know itz the control centre of cells, and directs cell's activities.
What do the ribosomes in the plant do?
Ribosomes are dense-looking granules formed of two parts. They may be attached to the endoplasmic reticulum or free in the cytoplasm. Ribosomes are the sites where amino acids are assembled into proteins in the process of protein synthesis.
Are enzymes carbohydrates or lipids or proteins?
The great majority of enzymes are proteins.Proteins are well suited to the job of catalysis, as they can fold into specific three-dimensional shapes that complement the shapes of their substrates.A few enzymes are RNA. For example, the activity of ribosomes depends in part on the catalytic activity of ribosomal RNA (rRNA).
Why do all cells need ribosomes?
All cells need ribosomes because that is where protein synthesis takes place. Proteins are required for enzymatic activity, cellular structures and functioning, metabolic activity, and are essential for life to occur. Even viruses, which are not considered living but organic molecules, are composed of proteins.Ribosomes are composed of ribosomal RNA and proteins. This RNA is synthesized and ribosome assembly takes place in the nucleolus of the nucleus in eukaryotes.Yes, all healthy animal cells contain ribosomes.

What is the primary activity of neuropsychologists?
The primary activity of neuropsychologists is assessment of brain functioning through structured and systematic behavioral observation.
If a toxin such as a bacterial toxin destroys ribosomes what cellular activity will be affected first?
protein syntheisis b/c DNA----> RNA----> proteins from ribosomes
Cellular components involved in metabolism that are influenced by temperature changes?
ribosomes, cell membrane and transport and enzyme activity
Why do cells need a ribosomes?
Every cell needs ribosomes because ribosomes make proteins by assembling chains of amino acids. An amino acid is any of about 20 different organic molecules that are used to make proteins. All cells need proteins to live. Thus, all cells have ribosomes.
What is the function of cell's nucleus?
It is the "Brain" of the cell. It controls all the cells activity. Inside the nucleus is the nucleolus, which makes ribosomes for the cell.
What is antonym of hybernation?
The antonym of hibernation is activity or wakefulness.
Does cardiac electrical activity immediately precede the contraction of the cardiac muscle?
Yes
How does pH affect plants growth?
becaues the plants will not have room for its root to grow
What characteristics does a successful external sphincter electromyography have?
In a normally functioning external sphincter muscle, the electromyogram will show increased electrical activity when the patient tightens the muscle and a little or no electrical activity when it is relaxed.
To fully appreciate the interaction of neural activity mental processes and the functioning of human communities it is most necessary to recognize that people are?
biopsychosocial
