It looks like you are providing a list of statements related to cellular transport mechanisms, particularly regarding the movement of water and glucose across cell membranes. I will help you fill in the blanks with the appropriate terms that complete the statements accurately:
- True For water to travel across the cell membrane at a substantial rate, the water molecules travel through protein channels known as aquaporins.
- True While water molecules are polar, they are also very small. One fact not mentioned in the video is that some water molecules are able to squeeze directly through the phospholipid bilayer due to their small size.
- True Charged ions are traveling through a cell membrane with the concentration gradient.
- False Cells lining the gut need to take in glucose, but at a certain time, the concentration of extracellular glucose is lower than the concentration already stored in the cells. (Cells typically use active transport in such situations.)
- True At a certain time, glucose is in a high concentration outside of a cell and needs to travel through the membrane into the cell.
Please adjust the veracity (True or False) for statements 10, 11, and 12 based on the context of your study or the specific concepts you are exploring.
