SC.912.L.18.1 Which of the following best compares the structures of lipids and carbohydrates?

• Both are made up of monosaccharide monomers, but lipids are hydrophobic and carbohydrates are hydrophilic.

• Both consist of carbon, hydrogen, and oxygen, but carbohydrates have repeating structural units and lipids do not.

• Both contain carbon and hydrogen, but carbohydrates also contain oxygen and lipids contain nitrogen.

• Both have a carbon backbone, but lipids also have an amino group and carbohydrates have a carboxylic acid group.

SC. 912.L.18.1 Some proteins catalyze biochemical reactions. If a genetic defect prevented a protein catalyst from being produced, which of the following do you predict would happen in the cell?

• The cell would find a different type of protein to catalyze the reaction.

• The reaction the protein catalyzes would proceed very slowly or not at all.

• The reaction the protein catalyzes would only occur in some places in the cell.

• The reverse reaction of the one the protein catalyzes would begin to proceed.

SC.912.L.14.2 Look at the cross section of a cell membrane of a eukaryotic cell. H+ ions are being pumped from

a low concentration to a high concentration.

How do you describe this type of transport across the cell membrane?

• Active transport

• Passive transport

• Facilitated Diffusion

• Co-transport

Many of the proteins in the human body are enzymes that catalyze chemical reactions. What is the relationship between enzymes and activation energy?

• When an enzyme catalyzes a reaction, it increases the activation energy of the reaction

• When an enzyme catalyzes a reaction, it increases the activation energy of the product.

• When an enzyme catalyzes a reaction, it decreases the activation energy of the reaction.

• When an enzyme catalyzes a reaction, it does not affect the activation energy of the

  reaction

The diagram below shows the bone structure of two animals. What do these two animals most likely have in common?

• They shared the same habitat.

• Their limbs served the same function.

• They are of the same species.

• They share a common ancestor.

Which student made the most accurate and precise measurements of the acorn?

• Student 1

• Student 2

• Student 3

• Student 4

Students conclude that water molecules, not sucrose molecules, moved into and out of the bag. Which statement best defends the conclusion?

• The distilled water in the beakers had the least change in mass.

• The change in mass indicates the movement of sucrose molecules.

• Only distilled water can cross a semipermeable membrane.

• Molecules only move when the sucrose concentration is above 5.00%.

A graph comparing the nitrogen content to the algae population size is shown below. The shape of the line on the graph indicates that nitrogen--------

• is a toxin to algae.

• is used by algae as a nutrient.

• supports the growth of algae competitors.

• prevents overgrowth of algae.

EOC Review: Which of the following best describes the role of chlorophyll in photosynthesis?

• A) Chlorophyll absorbs light energy and converts it into chemical energy.

• B) Chlorophyll stores energy in the form of ATP.

• C) Chlorophyll releases oxygen as a byproduct of photosynthesis.

• D) Chlorophyll transports water and nutrients within the plant.

EOC Review: In an experiment, a student measures the temperature change of water when a salt is dissolved in it. What type of reaction is this?

• A) Exothermic, because it releases heat.

• B) Endothermic, because it absorbs heat.

• C) Neutralization, because it involves an acid and a base.

• D) Combustion, because it involves burning.
