What are the enviromental factors that affect enzyme action?

Answer 1

Temperature: increasing the temp. will increase the reaction rate of any reaction

pH of solution: also effects the shape of the enzyme by changing the interactions of charges on the acidic (- charge) and basic (+ charge) amino acids.

Number of substrate and/or enzyme molecules available:the amount of workers vs. materials and vice versa. Presence of inhibitors: Competitive - action at the active site, similar molecules in shape

Non-competitive / allosteric - ('other' 'shape')

Answer 2

Environmental factors that affect enzyme action include temperature, pH levels, substrate concentration, and the presence of inhibitors or activators. Changes in these factors can alter the shape and function of enzymes, thereby influencing the rate at which they catalyze reactions. Optimal conditions for enzyme activity vary depending on the specific enzyme and its biological role.

Answer 3

Temperature, pH, cofactors, substrate and enzyme concentration, Inhibitors (competitive and non- competitive)

Allosteric enzyme and negative feedback mechanism e.g. in metabolic pathways

Answer 4

Things like pH and temperature affect it. Environmental conditions change the shape of enzymes irreversibly so that it won't work anymore. Like a lock and key, if someone melted your key then you would need a new one. ;)

Answer 5

That is difficult to answer without details. What kind of enzymes and in what context?

But enzymes are made of protein so they undergo the same problems a cell or protein would in different environments.

They denature and will coagulate in high temperatures, can freeze causing membranes damaged, will burst under the wrong moisture conditions (hyper/hypotonic solutions), and can be effected by other molecules present in the environment (catalysts speed reaction and inhibitors stop a reaction) depending on what enzyme is at work.

Most are also functional only within a specific acidic or alkaline range, so pH is important in beginning and ending an enzymes activity.

Answer 6

Enzyme's work best at a pH of 7.4 and if it's too high the enzyme will stop working.

Answer 7

Variations in temperature, pH and ionic concentrations.

Answer 8

High temperature>50 degrees C, none optimal pH (varies for the enzyme), heavy metals

Answer 9

1: pH

2:temp

3:ions present

4:substrate concentration

5:inhibitors

6:activators

7:product inhibition

Answer 10

Enzymes are affected by temperature, the amount of the substrate that they are acting on and the amount of product. All of these change how they work.
