How are egg cell adapted to do its job?
For one, it has lots of cytoplasm, to support the many divisions that it undergos. And the second adaptation, when a sperm cell interacts with it, the cell membrane changes immediately, to become impenetrable to any other sperm cells.
Can definite changes in the glycocalyx of the cell membrane be seen when the cell is becoming cancerous?
Yes, changes in the glycocalyx of the cell membrane can be observed during cancer progression. These changes may include alterations in composition, thickness, and structure, which can affect cell adhesion, migration, and signaling pathways. Monitoring glycocalyx modifications can provide valuable insights into cancer development and progression.
When does the cell membrane become impermeable?
The cell membrane becomes impermeable when it loses its integrity, typically due to damage or changes in its structure. This can prevent substances from freely moving in and out of the cell, disrupting essential cellular processes.
What is the structure that helps assure only a single sperm fertilizes an egg?
The zona pellucida is a glycoprotein layer surrounding the egg that helps prevent multiple sperm from fertilizing it. Upon fertilization, the zona pellucida changes its structure to prevent other sperm from entering the egg.
What is the stimulus that changes the resting membrane?
The stimuli that can change the resting membrane potential of a cell include changes in ion concentrations inside or outside the cell, neurotransmitter binding to receptors, and mechanical deformation of the cell membrane. These changes can lead to the opening or closing of ion channels, altering the flow of ions across the membrane and affecting the cell's resting membrane potential.

What is the first part of a cell that is affected when the PH is changed?
The cell membrane is the first part of a cell that is affected by changes in pH. A significant change in pH can alter the structure and function of the cell membrane, leading to disruptions in transport processes and cell signaling.
What is the stimulus that changes the resting membrane?
The stimuli that can change the resting membrane potential of a cell include changes in ion concentrations inside or outside the cell, neurotransmitter binding to receptors, and mechanical deformation of the cell membrane. These changes can lead to the opening or closing of ion channels, altering the flow of ions across the membrane and affecting the cell's resting membrane potential.
What membrane proteins is responsible for binding hormones that can trigger changes in the cells activity?
The membrane proteins responsible for binding hormones and triggering changes in cell activity are called hormone receptors. These receptors are typically located on the cell membrane and can be categorized into different types based on their structure and mechanism of action. Upon hormone binding, these receptors initiate signal transduction pathways that lead to specific cellular responses.
What is the function of the otolithic membrane?
The otolithic membrane is a structure in the inner ear that covers the hair cells of the utricle and saccule. It plays a role in detecting linear accelerations and head tilts, which helps in sensing changes in the position and movement of the head.
What happens first mitotic cell division in a testis or the process of fertilization?
