n chemistry, acids and bases have been defined differently by three sets of theories. One is the Arrhenius definition, which revolves around the idea that acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (H+) ions while bases produce hydroxide (OH-) ions in solution.

What types of materials are expelled from cells during exocytosis?
alex41 [277]

Large molecules such as hormones materials are expelled from cells during exocytosis

<u>Explanation:</u>

The materials inside the cells are transferred to the outside of the cell and this manner is termed as  Exocytosis. This method is termed as a kind of active transport since it needs energy for this transformation process. One of the major purposes of this process is to discharge trash matters like hormones and proteins.

For a cell to cell transmission and chemical signal messaging these methods are essential. Proteins that are newly generated are transferred to the peak of the plasma membrane by exocytosis. There are three general pathways of exocytosis.

A woman consumes 500 grams of carbohydrates, 30 grams of protein, and 75 grams of fat in one day. how many total kcalories has s
DedPeter [7]
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%
