Brainlies asap! : ) describe how proteins are used in active and passive transport. how do they differ?

Active transport require the cell to expand energy whilst Passive transport require no energy from the cell in active transport.

Passive Transport moves molecules across membrane without the use of energy by the cell.

-Simple diffusion

-Facilitated diffusion

-Osmosis

Active Transport uses energy (ATP) to move molecules across membrane.

-Protein pumps

-Exocytosis

-Endocytosis (Phagocytosis & Pinocytosis)

stress fractures occur largely in the feet and legs and are common in sports that require repetitive impact, primarily running/jumping sports such as gymnastics or track and field.
