Calcium must be actively pumped back into the terminal cisterns of the sarcoplasmic reticulum to terminate the contraction and relax the skeletal muscle. For every Ca2+ transported, one ATP molecule is hydrolyzed.

What is the significance of maintaining a balance in calcium concentration inside and outside the cell?

Maintaining a balance in calcium concentration inside and outside the cell is crucial for various cellular functions. Calcium plays a key role in cell signaling, muscle contraction, nerve transmission, and enzyme activation. An imbalance in calcium levels can disrupt these processes, leading to cell dysfunction and potentially harmful effects on the body. Therefore, maintaining the right balance of calcium is essential for proper cellular function and overall health.


What factors contribute to the membrane potential of a cell?

There are many factors that contribute to the membrane potential of a cell. The driving force of ions which are a summation of voltage gradient and concentration gradient are an important one. Also other proteins and amino acids contribute to the cell's membrane potential.


Nephrons located close to the medulla with loops of henle that extend deep into the renal pyramids are called?

These nephrons are called juxtamedullary nephrons. They play a key role in establishing concentration gradients in the kidney that are necessary for water reabsorption and urine concentration.


How does the regulation of blood calcium concentration exemplify negative feedback and homeostasis?

Calcitonin hormone lowers the blood calcium level. Parathormone or parathyroid hormone rise the calcium level. Vitamin D perform the some what complicated role. Together they maintain the calcium level almost precisely. This is not the precise and expert answer.


Which affects the rate of diffusion through a semipermeable membrane steeper concentration of gradients higher temperatures or the size of the molecule diffusing?

Steep concentration gradients and higher temperatures both increase the rate of diffusion through a semipermeable membrane. The size of the molecule diffusing also plays a role, as smaller molecules generally diffuse more quickly than larger ones due to their ability to move through the membrane more easily.

Which of these is a receptor for calcium ions?

The calcium-sensing receptor (CaSR) is a receptor specifically activated by calcium ions. It plays a crucial role in maintaining calcium homeostasis in the body by regulating the levels of calcium in the blood.

Is calcium a fiber?

No, calcium is a mineral, not a fiber. Calcium is essential for maintaining strong bones and teeth, while fiber is a type of carbohydrate found in plant-based foods that helps with digestion and can promote overall wellness.
