Answer:
an enzyme is a biological catalyst that increases the rate of a chemical reaction.
Explanation:
so it is true
Answer:
Within all lifeforms on Earth, from the tiniest bacterium to the giant sperm whale, there are four major classes of organic macromolecules that are always found and are essential to life. These are the carbohydrates, lipids (or fats), proteins, and nucleic acids. All of the major macromolecule classes are similar, in that, they are large polymers that are assembled from small repeating monomer subunits. In Chapter 6, you were introduced to the polymers of life and their building block structures, as shown below in Figure 11.1. Recall that the monomer units for building the nucleic acids, DNA and RNA, are the nucleotide bases, whereas the monomers for proteins are amino acids, for carbohydrates are sugar residues, and for lipids are fatty acids or acetyl groups.

Answer:
Triglycerides
Explanation:
Triglycerides are a kind of fat, the most common type in the body. Triglycerides can come directly from foods, such as oils, butter, and other fats, and they can be created by a person’s body when that individual consumes more calories than his or her body needs as a way of storing those surplus calories.
The medical term for having elevated levels of triglycerides is hypertriglyceridemia.
In fasting laboratory tests, a normal triglyceride level is below 150 milligrams per deciliter (mg/dL). High is considered 200 to 499 mg/dL. Very high is over 500 mg/dL.
High triglyceride levels can increase risk for heart disease, stroke, and nerve damage.
Answer:
Một phản ứng enzym thường bao gồm một chuỗi các bước như liên kết cơ chất không hóa trị, cấu hình lại hình học của enzym ở trạng thái liên kết, sự biến đổi hóa học của cơ chất thành sản phẩm và giải phóng sản phẩm.

The statement water is easily polluted..... is true. Water is pretty much the world's best solvent. So even toxic substances are easily dissolved in it and when that happens they pollute the water.
