To calculate the energy offered from food, multiply the number of grams of protein, carbohydrate, and fat by 4, 4, and 9, respectively.
Then add the results together.
Given: 500 grams of carbohydrates, 30 grams of protein, and 75 grams of fat in one day.
500 grams x 4 kcal/g = 2000 kcal
30 grams x 4 kcal/g = 120 kcal
75 grams x 9 kcal/g = 675 kcal
= 2795 kcal
From this data, you can calculate the percentage of k calories each of the energy nutrients give to the total.
Solution:
2000/2795 * 100% = 72% from carbohydrates
120/2795 * 100% = 4% from protein
675/2795 * 100% = 24% from fat
Total: 100%
Ionic bonds result when electrons are tranfered between atoms. Covalent bonds result when valence electrons are shared between atoms. You should be able to identify whether an ionic or covalent bond is being formed between atoms.
Answer:
Nucleic Acids
Explanation:
Nucleic acids are made out of nucleotides and they come in two forms: Deoxyribonucleic Acid (DNA) and Ribonucleic Acid (RNA). DNA holds the code of life, in other words, it holds the code for making proteins that are essential in building cells, tissues, and organs. DNA is found in the nucleus of a cell.
1. Enzyme interacts with substrate
.
2. Enzyme may undergo a conformational change to capture the substrate ("induced fit" model)
3. Enzyme-substrate complex may undergo several changes to form the product(s).
4. The product(s) are released
.
5. The enzyme returns to its original form. It is then ready to do the cycle all over again.
