What else can I help you with?
How much larger than a sperm cell is an ovum?
An ovum is typically around 80 times larger than a sperm cell. This size discrepancy is due to the differences in function and composition of the two cells, with the ovum containing the necessary components to support early embryonic development.
What can change the way an enzyme acts?
Enzyme activity is affected by other molecules, temperature, chemical environment (e.g., pH), and the concentration of substrate and enzyme. Activators are molecules that encourage enzyme activity, and inhibitors are enzymes that decrease enzyme activity. Sometimes a cofactor is necessary for the enzyme to work.
What organ has an acid necessary for enzyme action to occur is found within structure?
Found in the stomach
What enzyme is activated by HC1?
HC1 (hydrochloric acid) activates pepsinogen into its enzyme form Pepsin.
What chemicals come out of the acrosome that help the sperm get into the egg?
The acrosome layer of sperm cells contain enzymes to break down the outer layer of the ovum to allow penetration by the sperm cell.
How does ovum prevent multiple penetrations of sperm cells along its periphery?
as soon as a single sperm fertilises the ovum a change of composition takes place in ovum's outer layer forming zona pellucida which prevents the penetration of other sperms.
What is the function of the enzymes int eh head of the sperm?
Enzyme Hyarulonidase is found mainly.It helps to degrade membranes around ovum
What is the Female Gamete?
The female gamete is an egg or ovum. It is produced in the ovaries and is necessary for sexual reproduction when fertilized by a male gamete (sperm).
What is the only enzyme necessary for transcription?
RNA Polymerase
What structure is an acid necessary for enzyme action?
stomach
What Vitamin is necessary for the production of an enzyme found in tears?
Vitamin A
Is a egg a female?
ovum ovum ovum
How much larger than a sperm cell is an ovum?
An ovum is typically around 80 times larger than a sperm cell. This size discrepancy is due to the differences in function and composition of the two cells, with the ovum containing the necessary components to support early embryonic development.
How does the ovum prevent multiple penetrations of sperm cells along it's periphery?
The ovum has a protective layer called the zona pellucida that hardens after the entry of one sperm cell, preventing additional sperm cells from penetrating. This process is known as the zona reaction and ensures only one sperm cell fertilizes the egg.
What can change the way an enzyme acts?
Enzyme activity is affected by other molecules, temperature, chemical environment (e.g., pH), and the concentration of substrate and enzyme. Activators are molecules that encourage enzyme activity, and inhibitors are enzymes that decrease enzyme activity. Sometimes a cofactor is necessary for the enzyme to work.
What are facts about an ovum?
its an ovum
Which enzyme is in the human sperm head?
The spem head or acrosome cap contains digestive enzymes such as hyaluronidase and acrosin which are used to lyse the outer wall of the ovum during fertilization
