What is maintaining homeostasis in a cell?

Cellular homeostasis involves maintaining a balance of several factors that make a cell healthy. This allows cells to maintain a higher concentration of sodium ions out the outside of the cell. Cells also maintain a higher concentration of potassium ions and organic acids on their inside.

What is a conformational change in biology?

The adjustment of a protein’s tertiary structure in response to external factors (e.g. pH, temperature, solute concentration) or to binding of a ligand.

How is Proteostasis maintained in cells?

Cellular mechanisms for maintaining proteostasis include regulated protein translation, chaperone assisted protein folding, and protein degradation pathways. Adjusting each of these mechanisms based the need for specific proteins is essential to maintain all cellular functions relying on a correctly folded proteome.

What is the medical dictionary definition of homeostasis?

n. A state of equilibrium, as in an organism or cell, maintained by self-regulating processes: The kidneys maintain homeostasis in the body by regulating the amount of salt and water excreted.

How do the organs work together to maintain homeostasis?

Each organ system performs specific functions for the body, and each organ system is typically studied independently.   However, the organ systems also work together to help the body maintain homeostasis. For example, the cardiovascular, urinary, and lymphatic systems all help the body control water balance.

How are negative feedback loops used to maintain homeostasis?

Negative feedback is a mechanism in which the effect of the response to the stimulus is to shut off the original stimulus or reduce its intensity.   Negative feedback loops are the body’s most common mechanisms used to maintain homeostasis.

How does the body return to homeostasis during childbirth?

Normal childbirth is driven by a positive feedback loop. A positive feedback loop results in a change in the body’s status, rather than a return to homeostasis. The first contractions of labor (the stimulus) push the baby toward the cervix (the lowest part of the uterus).
