What is the purpose of membrane transport proteins, such as carrier and channel proteins?

Diffusion moves molecules in this direction

A cell is treated with a drug that prevents protein synthesis. The structure most likely to be affected is

A reaction where a complex molecule is broken down into smaller molecules is called:

CHOOSE ALL THAT APPLY: Maltase is an enzyme that breaks apart one molecule of Maltose to produce two simple sugars. The reaction is below. Which of these are true about this enzymatic reaction?  

In Experiment B, only starch can diffuse. What will be the final starch concentration in each environment after equilibrium has occurred?

Which of these molecules CAN passively diffuse through the cell membrane without the aide of transport proteins?

Researchers designed an experiment to see the effects of different toxic compounds on prokaryotes. In the questions below, answer which organelles or structures were affected, along with a brief rationale. A. Compound 1 caused the bacteria to dissolve. B. Compound 2 prevented enzyme synthesis. However, the DNA was not affected C. Compound 3 prevented enzyme synthesis. However, the ribosomes were still intact D. Compound 4 had no effect on the bacteria. It was designed to inhibit golgi activity. Explain why this compound had no effect E. Compound 5 had no effect on the bacteria. It was designed to inhibit mitochondrial activity. Explain why this compound had no effect.

When an individual is dehydrated, their blood has the same amount of solutes, but less water. If severe enough, their blood can become:
