12/15/14

Question Answer
Living cells maintain a _____ by controlling materials that enter and leave. Balance
Without this ability, the cell cannot maintain _______ and will die. Homeostasis
The cell must regulate internal concentrations of water,______, and other nutrients and must eliminate waste products. Glucose

How do living cells maintain a chemical balance?

The primary means by which the cell maintains balance is via sensors; without being able to detect whether the system is in balance or not, the cell would not know what to do to maintain it. Some of the sensor systems that the cell uses are enzymes and receptors.

Which property of a cell allows it to maintain homeostasis?

One way that a cell maintains homeostasis is by controlling the movement of substances across the cell membrane. The lipid bilayer is selectively permeable to small, nonpolar substances. Proteins in the cell membrane include cell-surface markers, receptor proteins, enzymes, and transport proteins.

How is homeostasis maintained in cells?

Homeostasis in an organism or colony of single celled organisms is regulated by secreted proteins and small molecules often functioning as signals. Homeostasis in the cell is maintained by regulation and by the exchange of materials and energy with its surroundings.

Which organelle helps maintain homeostasis by controlling what goes in and out of a cell?

plasma membrane
The plasma membrane (cell membrane) forms a barrier between the cytoplasm inside the cell and the environment outside the cell. It protects and supports the cell and also controls everything that enters and leaves the cell.

Why is it important for cells to maintain homeostasis?

Living organisms need to maintain homeostasis constantly in order to properly grow, work, and survive. In general, homeostasis is essential for normal cell function, and overall balance. For this process to function properly, homeostasis helps our body to keep both water and salt balance level.

How do cells maintain homeostasis quizlet?

Cells maintain homeostasis by performing the processes of active and passive transport to ensure dynamic equilibrium. Cells maintain homeostasis of pH by emitting either basic fluids or acidic fluids depending on the pH level.

How does the cell maintain homeostasis balance in its internal and external environment?

Control of Homeostasis Homeostasis is maintained by negative feedback loops within the organism. In contrast, positive feedback loops push the organism further out of homeostasis, but may be necessary for life to occur. Homeostasis is controlled by the nervous and endocrine systems in mammals.

Which organelle helps maintain homeostasis by controlling what enters and leaves the cell?

The plasma membrane

What maintains homeostasis?

Homeostasis is mainly controlled by the organs in the central nervous system and the endocrine system (hormones). Organs in the two systems send commands to other organs in other systems to allow them to carry out certain functions.

How do you maintain homeostasis?

1 Answer

  1. Temperature. The body must maintain a relatively constant temperature.
  2. Glucose. The body must regulate glucose levels to stay healthy.
  3. Toxins. Toxins in the blood can disrupt the body’s homeostasis.
  4. Blood Pressure. The body must maintain healthy levels of blood pressure.
  5. pH.

What organelles maintain homeostasis?

Biology- Cells

A B
One important organelle that helps maintain homeostasis by moving supplies from one part of the cell to the other is the endoplasmic reticulum
A cell’s ATP is produced in the mitochondrion
Numerous hairlike organelles that protrude from the sruface of a cell and are packed in tight rows are called cilia
