How is the synthesis of a constitutive enzyme stopped?
by changing their catalytic activity
Which activity is an example of the life process known as synthesis?
starch is formed by the chemical bonding of glucose
What are the mechanisms ofthe cell membrane?
aNAINST ANTIBIOTICS: Inhibition of Cell Wall Synthesis (most common mechanism) Inhibition of Protein Synthesis (Translation) (second largest class) Alteration of Cell Membranes Inhibition of Nucleic Acid Synthesis Antimetabolite Activity
After a cell was treated with a certain chemical the ribosomes stopped functioning which cell activity was immediately affected by this change in ribosome funcation?
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 enzyme synthesis?
the production of enzymes by activity including combining chemicals, which is the definition of synthesis.

What adjectives are associated with the activation-synthesis hypothesis?
Some adjectives associated with the activation-synthesis hypothesis include speculative, controversial, and innovative.

synthesis of proteins. And since the synthesis of proteins is necessary for maintenance of the cell, most of the processess will be stopped afterwards.
WHAT model of dreaming proposes that dreams are side-effects of neural activity in subcortical areas of the brain?
activation-synthesis model
What has the author Naomi Raeburn written?
Naomi Raeburn has written: 'The synthesis, reactions and potential biological activity of oxindolespirobicycloheptanes and octanes. 1978'
Four ways hormones may alter cellular activity?
1) Change in membrane permeability and/or voltage 2) Enzyme activation/inactivation 3) Initiation of secretory activity 4) Synthesis of regulatory molecules such as enzymes
