Question

1. enzymes are a type of protein that act as

what does this mean?
why would life not be possible without enzymes.

1. this chart shows the significance of the primary structure of amino acids. why was

the one amino acid different between normal hemoglobin and sickle cell hemoglobin?

1. what has happened to this protein and what is the process called?

what is something that can cause this to happen?

1. ____ and ____ are the two types of nucleic acids.
2. what are the monomers of nucleic acids called?

how many are there?

Explanation:

1. Enzymes are biological catalysts. They speed - up chemical reactions in the body. Without them, reactions would occur too slowly to sustain life.
2. A single amino - acid change in the primary structure of hemoglobin (due to a genetic mutation) causes sickle - cell anemia. The abnormal hemoglobin causes red blood cells to sickle, affecting their function.
3. The protein has undergone denaturation, which is the disruption of its native three - dimensional structure. Heat, pH changes, and chemicals can cause denaturation.
4. Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are the two types of nucleic acids.
5. The monomers of nucleic acids are called nucleotides. There are four main types in DNA (adenine, thymine, cytosine, guanine) and four in RNA (adenine, uracil, cytosine, guanine).

Answer:

1. Enzymes are biological catalysts. Life would not be possible without them as body's chemical reactions would be too slow.
2. A genetic mutation led to a single amino - acid difference, causing sickle - cell anemia and abnormal red - blood - cell shape and function.
3. The protein has denatured. Causes include heat, pH changes, and chemicals.
4. DNA; RNA
5. Nucleotides; Four main types in each of DNA and RNA
