Answer:
Role of enzymes in the human body
Explanation:
The chemical reactions that keep us alive - our metabolism - rely on the work that digestive enzymes do. They help to accelerate (catalyze) chemical reactions in the human body.
In some cases, they can cause a chemical reaction millions of times faster than they would without them.
Important functions of enzymes:
Digestive enzymes help the body break down larger complex molecules into smaller ones such as glucose, so it uses them as fuel.
Every cell in our body contains DNA. Each time the cell divides, this DNA must be copied. The process is called DNA replication . Enzymes help in this process by developing the DNA helix and copying the information.
Liver enzymes break down toxins in the body.
Enzymes are especially needed for respiration, digestion, muscle and nerve function, among other important roles.
Answer:
C. Enzymes are proteins that speed up the process of chemcially breaking down food molcules.
Explanation:
A B-cell uses its surface antibodies as receptors to attach to specific antigens before they are taken in. By what mechanism does a B cell engulf an antigen
Answer:
[tex]\huge\boxed{\sf Endocytosis}[/tex]
Explanation:
B-cells engulf an antigen by endocytosis.
Endocytosis:
The process by which cell takes up external materials by fusing them with plasma membrane is called endocytosis.
After engulfing the antigen, B-cells become sensitive to the pathogen.

~AH1807Explain how mountain ranges might be affected by Deposition.
SCIENCE
Answer:
It effects it because there's a possibility it can reduce the mountains to a smaller structure (breaking down), like a plateau, which would for sure leave a change in the landforms

Answer:
The green algae are subdivided into the chlorophytes and the charophytes.
Explanation:
Offspring that result from crosses between parents with different traits.
This type of receptor, once bound by ligand, can change conformation to allow specific substances to flow down their concentration gradient. This type of receptor is referred to as ____________ . This type of receptor is not an enzyme itself, but is bound to a protein that can exchange GDP for GTP and then stimulate effector proteins, which are usually enzymes. This type of receptor is referred to as ____________ . This type of receptor is a transmembrane receptor. It has an extracellular domain that binds to ligand, and an intracellular domain that can directly phosphorylate other proteins. This is an example of ____________ . This type of receptor binds to hydrophobic ligands. This type of receptor is referred to as ____________ .
Answer:
Channel linked receptor
Coupled receptor
An enzymatic receptor
An intracellular receptor
