Question

1 multiple choice 2 points what does it mean that the plasma membrane is semipermeable? only molecules soluble in lipids can pass freely through the membrane only large molecules such as amino acids and glucose can pass freely through the membrane only water can pass freely through the membrane only ions can pass freely through the plasma membrane 2 ordering 2 points put the stages of aerobic respiration in order. 1 electron transport chain 2 glycolysis 3 intermediate reaction 4 krebs cycle

Explanation:

The plasma - membrane is semi - permeable meaning it allows certain substances to pass through while restricting others. Small, non - polar (lipid - soluble) molecules can pass freely through the lipid bilayer of the plasma membrane. Aerobic respiration has a specific sequence of stages. Glycolysis is the first step where glucose is broken down. Then comes the intermediate reaction, followed by the Kreb's cycle which further breaks down the products from the intermediate reaction, and finally the electron transport chain which generates a large amount of ATP.

Answer:

1. Only molecules soluble in lipids can pass freely through the membrane
2. 2. Glycolysis
3. 3. Intermediate reaction
4. 4. Kreb's cycle
5. 1. Electron transport chain
