1) You are studying the uptake of a certain molecule into cells that produce no ATP. You discovered that it in fact does become transported into the cell. To further your research, your colleague

decides to do the same experiment but supplies the cell with ATP. He discovers that the cell

transports more of the molecule intracellularly.

a. Describe the difference in transport between your experiment and his. Explain. (10pts)

b. What characteristics must this molecule have in order to use both types of transport?

This is s cute awee : (( . well if she's showing you signs that she may like you , then shoot your shot ! don't be afraid . & if you're unsure that she's giving you these signs , then wait out for a little bit . most girls are different . some may act really sweet , but only bc you're a good friend of hers . that , or she might like you . you just never know . but i think you should sit down with her & tell her how you feel . but don't be awkward & shy . just be straight up & tell her how you feel . if the feelings aren't mutual , then don't cry about it . you need to respect her decision & look for others in the world . feelings can be difficult & confusing , but don't be afraid to show them . i say you play it out & if you're still unsure about it , talk to her . - rach
