List and describe three factors that affect how quickly enzymes can work to catalyze reactions
Lilit [14]

Answer:

The correct answer is - temperature, pH, substrate concentration.

Explanation:

Various factors affect the rate of enzymatic reaction such as pH, temperature, substrate concentration, availability of activators or inhibitors in the reactions, and enzyme concentration.

Temperature: Temperature affects the rate of the enzyme-catalyzed reactions. Like most of the reactions with an increase in temperature rate of enzymatic reaction also rises up to a maximum level and then declines if the temperature continues to increase as enzyme denatures after a particular temperature.

pH: Similar to the temperature pH also increases the rate of reaction up to a maximum level and then declines the rate as every enzyme acts only at an optimum pH range.

Substrate concentration: If the substrate concentration is increased gradually while the concentration enzyme remains constant, the rate of reaction will increase until it reaches a maximum.

Match the digestive organ on the left with its function.
RUDIKE [14]

Answer:

pancreas: secretes digestive enzymes into the small intestine

esophagus: the place where peristalsis takes place

small intestine: area of the digestive tract where most nuturients are absorbed

stomach: area of the digestive tract that follows the esophagus

large intestine: area of the digestive tract where mostly water is absorbed

Explanation:

peristalsis: so the food can move down towards your stomach, independently of gravity

pancreas: helps your stomach become the ultimate weapon to destroy anything that gets in there with its enzymes

small intestine: it is really really long -> more time to absorb nutrients

large intestine: like a farm of bacteria, the most exotic things that somehow made it through all the way here are finally destroyed -> also, water absorbtion: your body wants to retain as much as possible, this is how and where stool formation takes place
