DOWN$1$ When red blood cells are placed into this type of solutionwater will rush into the cell, which could cause the cell toburst$3$ This domain of a membrane protein is probably composedof non$-$polar hydrophobic amino acids$5$ The Na $/$K pump is an example of this type of transporter where $2$ molecules are moving in opposite directions$7$ As the surface area of a cell increases, the surface area$-$to$-$volume ratio $\_\_\_\_\_\_\_\_\_\_\_\_\_8$ Where DNA is located in archaea and bacterial cells$11$ This type of transport requires the direct or indirectsupply of ATP, allowing movement of molecules up oragainst their concentration gradient$12$ Because animal cells lack a cell wall, they secrete proteins$($such as collagen$)$ into the extracellular $\_\_\_\_\_\_\_\_\_\_\_$ tohelp cells bind together and for additional protection$\mathrm{.}14$ associated with cell movement of both prokaryotic andeukaryotic cells$18$ Phospholipids and $\_\_\_\_\_\_\_\_\_\_\_\_\_\_$ make up a majorityof the cell membrane$21$ Newly synthesized proteins are accepted into the golgiapparatus at this face for further modification, packagingand transport. Proteins then exit the Golgi through thetrans face.
