Are these two statements TRUE or FALSE?

1. The main barrier to glucose transport across the cell membrane is its electrochemicalgradient.

2. All phospholipids have identical head groups that contain a phosphate

Solution

1. The main barrier to glucose transport across the cell membrane is its electrochemicalgradient. ---> FALSE (glucose is not an ion, the main barrier to glucose transport across the cell membrane is its concentration gradient)

2. All phospholipids have identical head groups that contain a phosphate ----> TRUE (The cell membrane is a phospholipid bilayer, which contains phospholipids in their structure. As the name indicates, the phospholipid contains phosphate and fatty acid molecules in its structure. )
