forces more LDL ("bad") cholesterol out of the body throughwaste elimination. | ||
keeps the blood circulating faster, even at rest, thereforecauses a decrease in total blood cholesterol. |

is not expensive. | ||
promotes cardiovascular endurance. | ||
is easy to perform. | ||

Multiple choice
ATP-ase.
cytochrome C.
NADPH.

True/Fale
Part 3
Alex, Kim, and Jenna have different levels of activity, and thus require a varied amount of calories per day. Alex is an athlete, and he requires 3500 calories per day to fuel his high intensity activity. Jenna is a secretary and is sedentary most of her day. Her low level of activity requires a mere 1800 calories a day, while Kim, a professional dancer, needs 2800 calories per day to fuel her moderate level of activity.
Jenna | Kim | Alex | |
Profession | Secretary | Professional Dancer | Athlete |
Level of Activity | Low | Moderate | High |
Caloric Needs | 1800 Calories/Day | 2800 Calories/Day | 3500 Calories/Day |
Fats are broken down in cellular respiration to generate the ATP needed to fuel our bodies. According to the Food and Drug Administration (FDA), the Percent Recommended Daily value for fats in a balanced diet should not exceed more than 30% of the total daily calorie intake. Fats provide 9 calories per gram.
Nutritional needs of Jenna
What question would this calculation answer?
Finding 30% of 1800 calories and then dividing by 9 calories per gram.
1800 calories x 0.30 = 440 calories
440 calories/9 calories per gram = 49 grams
Multiple Choice
How many grams of fat can Jenna consume in one meal?
How many fat calories can Jenna consume each day?
How many calories are found in 9 grams of fat?
How many grams of fat can Jenna consume each day?
Part 4
Proton pumps are protein complexes that
Multiple Choice
synthesize water from hydrogen and oxygen.
break down water into hydrogen and oxygen.
move hydrogen ions across cell membranes.
move electrons through the cell membrane.
Part 5
As protons move through the proton pump,
Multiple Choice
the membrane becomes more permeable to the hydrogen ions.
the concentration of hydrogen ions inside and outside the cell reaches equilibrium.
they build up on one side of the membrane, producing a concentration gradient.
conformational changes occur within the membrane proteins.
Part 6
The transfer of hydrogen ions across the membrane generates a potential energy gradient.
