Which of these are able to pass through the cell membrane? (Select all that apply.) oxyger
organelles
carbon dioxide

oxygen and carbon dioxide

Explanation:

Small, uncharged substances such as oxygen and carbon dioxide can pass through the membrane by diffusion, down their concentration gradient.

Larger molecules or charged molecules cannot easily diffuse through the plasma membrane, and require the help of proteins to get into and out of the cell.

Organelles are relatively large molecules, and likely need a process called endocytosis to pass through the cell membrane into the cell, or exocytosis to pass through the membrane outside of the cell.

Endocytosis and exocytosis rely on membrane-bound vesicles to move substances across the membrane to their destination.

endocrine glands secrete hormones into the blood stream near them; the hormones then travel in our bloodstream until it reaches its destination, called a target cell, in distance parts of the body. in the target tissue, hormones lock onto the target’s plasma membrane, called the receptor site.
