This week we are covering macromolecules (carbohydrates, proteins, nucleic acids, and lipids), the structure and function of cells, including cellular transport mechanisms. Find a news article from Science Daily (or another credible news source) that describes a recent research study that relates to something you found interesting in this week's readings. The article should be less than 3 years old and not already discussed by another student.

Understand the process & role of membrane bulk transport in cell function - for example, passive & active transport as well as pinocytosis & phagocytosis.

cell size maximizes the ability of diffusion and motor proteins to transport nutrients and waste products.

It is a transport protein that undergoes conformational change (change in shape) when transporting molecules in and out of the cell.

Which type of cellular transport moves molecules across the membrane by expending energy?

How do molecules move that are facilitated by active transport?lower concentration to higher concentrationthrough the cell membranehigher concentration to lower concentration
