The maximum rate of enzyme reaction that can be used is

Metabolism and regulation of enzymes.

An important feature of life is homeostasis, maintenance

Our thousands of different enzyme functions contribute to
Metabolic homeostasis. For the rest of this chapter, we
The role of enzymes in regulating and regulating metabolism will be explored. The activity of enzymes in cells is possible.

Activate or block in various ways, thus balancing
An enzyme is not needed to make sure it works.
Some enzymes have mechanisms that change the rate at which they react, thus making enzyme target points.
The whole sequence of chemical reactions can be arranged. Finally, we find out what the environment is like –
Temperature and pH – affect the activity of enzymes.

Metabolism is organized into pathways
The metabolism of an organism is the sum of the biochemistry
There are reactions to this. metabolism
Energy stored in raw materials and potential forms
used by living cells. Metabolism has the following sequence
Catalytic chemical reactions are called pathways.

In these sequences, the product of one reaction is the substrate for the next:
Some metabolic pathways are anabolic, integrated

Some inhibitors occur naturally in cells; Others are artificial. Naturally occurring inhibitors regulate metabolism; can be artificial

Removal of the enzyme’s natural reversible inhibitor increases the enzyme’s catalytic rate.

irreversible obstacle. some resistors are tied together
In some lateral chains where an enzyme is active, it is permanently inactivated by destroying the enzyme.
Its ability to interact with its normal substrate. We described aspirin at the beginning of this chapter, which adds a
The acetyl group at a serine residue, which is active in cyclooxygenase, inhibits the chemical reaction of this serine.
Another example of an irreversible inhibitor is DIPF (diisopropylphosphorofluoride), which reacts with serine.
. DIPF is an irreversible inhibitor of acetylcholinesterase, an enzyme required for the proper transmission of excitation from one nerve cell to another.

All repressions are irreversible.
Some inhibitors may be sufficient for a specific enzyme.
The natural substrate is still related without moving to its active site
The enzyme is different in that it does not promote the chemical
