Biology Enzymes and Cell Transport Quiz

The movement of molecules from a region of high concentration to a region of low concentration, driven by the random motion of molecules.

Temperature is a crucial factor that influences the activity of enzymes. Each enzyme has an optimal temperature range, and deviations from this range can significantly affect its activity.

Active transport requires energy to move molecules across a cell membrane against their concentration gradient, from an area of low concentration to an area of high concentration.

Osmosis is the movement of water molecules across a selectively permeable membrane from an area of high water concentration to an area of low water concentration.

High temperatures can cause enzymes to denature, altering their three-dimensional shape and rendering them inactive.

pH can affect enzyme activity by influencing the enzyme's shape and function. Each enzyme has an optimal pH range, and deviations from this range can decrease its activity.

Increasing the temperature generally increases enzyme activity, but this effect is only true within a certain range. Beyond this range, high temperatures can lead to enzyme denaturation and inactivation.

The concentration of the solution is the primary factor determining the rate of diffusion. A higher concentration gradient leads to a faster diffusion rate.
