Enzymes are strict of what factors to function

Temperature, Ph, Substrate concentration

What’s collision theory

Likelihood of a reaction to occur is dependent of the amount of successful collisions occurring between molecules.

Why does the rate of chemical reaction increase with higher temperature

An increase in temperature means an increased likelihood in successful collisions between molecules

What happens to Rate of reaction when the “optimal” temperature is reached

From there the rate of reactions decreases all the way to zero

Why does the rate of reaction slow down after passing optimal tempeatur

The folds of the enzyme are disrupted as a result of increased temperatures. Since fusion between enzymes and substrates is so specific— after being denatured— it can no longer catalyse any reactions

In most cases— is denaturation permanent

Yes

Enzymes work best at what temp

its optimal temp

What is an organisms optimal temperature dependent on

Its environmental circumstances— eg thermophhiles require more heat to reach its optimal temperature

Recall the ranges of Ph

1-6 is Acidic, 7 is neutral, 7+ is alkaline

Do all enzymes perform best at the same Ph level

NO, its optimal temperature varies on environmental circumstances

What happens if an enzyme is placed into an unsuitable pH substance

Bonds holding the protein together weaken and denaturation occurs. Rate of reaction slows until it stops

pepsin function and wheres it found+ its ph level

breaks down protein within stomach ACID

wheres trypsin and pancreatic lipase found and its ph level

duodenum in the small intestine withh ALKALINE environment

What happens to the rate of reaction when theres excess substrate molecules

It increases and theres now more enzyme concentration

Process of increasing substrate concentration in a limited amount of enzymes

After the optimal substrate concentration is reached— with enzymes occupied by other substrate molecules— the rate of reaction is at its maximum. Any more substrate concentration wont impact reaction rate— it stays the same
