Exam 5: The Working Cell

Scenario Cellular respiration converts the energy of fuel molecules to a form of energy that a cell can use to perform work. In an average day, most adult humans need to consume about 2,000 Calories to maintain their health. However, the exact amount of dietary Calories a person needs depends upon many factors, including the person's age, physical activity, size, and health. Foods that we consume vary greatly in their nutritional content and quality. A large hard-boiled egg, for example, has about 75 dietary Calories and contains about 70% of our recommended daily intake of cholesterol. -The amount of dietary Calories in one hard-boiled egg could raise the temperature of ________.

In a hypotonic solution, a plant cell will ________.

Enzymes increase the rate of a reaction by ________.

What cell transport is modeled by the diagram below?

Osmosis can be defined as ________.

A balloon that is permeable to water but not to glucose contains a 10% glucose solution. A beaker contains a 5% glucose solution. Which statement correctly classifies the solutions?

Examine the cells below. Cells with a higher concentration of ions than the surrounding medium tend to ________.

A boulder at the top of a hill contains ________ energy.

Which statement about an enzyme is TRUE?

The combination of sucrose, sucrase, and water produces sucrase, glucose, and fructose. Which component of the reaction is the enzyme?

Ten kilocalories are equivalent to ________ calories.

How does the figure below represent the relationship between energy and ATP?

Glucose molecules provide energy to power the swimming motion of sperm. In this example, the sperm are changing ________.

A balloon contains a 10% glucose solution. The balloon is permeable to water but not to glucose. A beaker contains a 5% glucose solution. What will happen when the balloon is submerged in the beaker?

This energy, stored inside of our food, is a form of ________.

An object at rest has no ________ energy, but it may have ________ energy resulting from its location or structure.
