Document Summary

Come from our food choices, fortified foods, natural health products, 1 calorie is the amount o energy it takes to warm 1 kg of water up by 1 deg c. Essential nutrients: cannot be synthesized by your body and must be provided by the diet phytochemicals, zoochemicals. Nutrients that are needed by the body in large amounts. The amount of energy they provide is measured in kilo-calories (kcal) Does not provide us with energy, but essential for different functions of the body. Involved in helping your body use the energy from carbohydrates, fat, and proteins. Involved in bone growth, vision, blood clotting, oxygen transport, tissue growth and development, myelination, methylation, genetics/dna, etc. Needed for bone strength, the transport of oxygen, and the transmission of nerve impulses. Water is also a macronutrient but does not provide energy. 60% of our body weight is made up of water. Vitamins: organic (contains carbon) molecules our body needs in order to function.

Background: In this assignment, you willinvestigate the chemical composition of the foods we eat as ourbodies break down food by the digestive process.

The USDA Nutrient Data Laboratory has posted a resourcethrough which you can investigate the chemical composition offoods. Go to the USDA Lab Link at USDA Nutrient DataLaboratory: http://ndb.nal.usda.gov/

Instructions

Type in a keyword, then select a food group using the drop-downarrow, then click "submit."
This pulls up a menu with lots of choices.
Choose one food choice, then click "submit"
Next choose a portion size, then click "submit"
This will bring up the nutritional informationneeded to complete the assignment.

Example:

Keyword: Apple
Select Food Group: Fruits and FruitJuice
Apples, raw, with skin.
One medium

Assignmentdetails:

A. Nutrition: Analyze the nutritionalcomponents of the food you select; and in your own words, answerthe following questions using the USDA Nutrient Data Laboratory Website as listed in the unit Web resources:

What was the food and portion size you chose?
Describe its composition in terms of carbohydrates, lipids, andproteins.
How many calories are in your food item? (Found in the Databaseas Energy Ã¢â¬â kcal)
List some of the most common vitamins and minerals in this fooditem.
Are there other important nutritional components of this fooditem? If so, list these. If not, say so.

B. Water:

How much of your food item is water?
Provide one reason why water is important for life. Toadequately answer this question, it will be necessary to explain areason for waterÃ¢â¬â¢s importance based upon its chemical and /orphysical properties.

C. Biological Molecule:

State the most abundant category of biological molecule in yourfood: carbohydrates, lipids, or proteins.
Describe the structure of this type of molecule, and itsprimary function(s). This section will not be a one sentence answer.In order to adequately Ã¢â¬ÅdescribeÃ¢â¬ an entire category ofbiological molecules, you will need to briefly review their basicmolecular structures and functions.

D. Recommendation:

After identifying the nutritional components, discuss WHY youwould or would not recommend this food item as part of a healthy,nutritious diet. Be sure to use references and guidelines such asthe Food Pyramid and Recommended Daily Allowances to support yourrecommendations.

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

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.
