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.
