What else can I help you with?
Does cerebrospinal fluid have the exact same composition as blood plasma?
No, cerebrospinal fluid (CSF) does not have the exact same composition as blood plasma. CSF is produced by the choroid plexus in the brain and is an ultrafiltrate of plasma with lower protein and glucose levels but higher chloride concentrations. Additionally, CSF plays a role in cushioning the brain and spinal cord, as well as removing waste products.
How is the reduction of plasma alanine concentration caused by gluconeogenesis?
Alanine is the major gluconeogenic amino acid. Plasma alanine is used to make glucose in the liver (Glucose-Alanine Cycle), and thus when this occurs plasma alanine concentration is decreased.
The movement of glucose molecules across a plasma membrane from an area of lower glucose concentration to an area of higher glucose concentration occurs due to?
active transport, specifically through a process known as secondary active transport or cotransport. This process relies on the use of energy generated by the concentration gradient of another molecule, usually sodium ions, to drive the movement of glucose against its gradient.
What best describes the Na and K concentrations across a neuron's plasma membrane?
The Na concentration is higher outside of the neuron's plasma membrane, while the K concentration is higher inside the neuron's plasma membrane. This creates an electrochemical gradient that allows for the generation and transmission of electrical signals in neurons.
Cells require glucose as a source of energy to carry out life processes. Large molecules like glucose cross the cell's plasma membrane by?
Large molecules like glucose cross the cell's plasma membrane primarily through facilitated diffusion, a process mediated by specific transport proteins known as glucose transporters. These proteins help transport glucose down its concentration gradient without using energy. In some cases, glucose can also enter cells via active transport, which requires energy to move glucose against its concentration gradient.
1 Plasma blood glucose is higher than whole blood glucose by what percentage?
i know it's higher than corresponding blood glucose concentration from 10 - 15%

Whenever the plasma glucose concentration exceeds the renal plasma threshold?
it shows in urine.

What is the normal constituents of CSF?
Normal constituents of cerebrospinal fluid (CSF) include water, electrolytes (such as sodium and potassium), glucose, and proteins (such as albumin). It also contains cells like lymphocytes and monocytes in low numbers.
What best describes the Na and K concentrations across a neuron's plasma membrane?
The Na concentration is higher outside of the neuron's plasma membrane, while the K concentration is higher inside the neuron's plasma membrane. This creates an electrochemical gradient that allows for the generation and transmission of electrical signals in neurons.
Connection between plasma osmolarity and total body water in mathematical equation terms?
Plasma Osmolarity =Total Body mOsm - Urine mOs-------------------------------------Total Body Water - Urine Volumeand: Total Body Osmolarity = PLasma Osmolarity x Weight x 0.6 Total Body Water = Weigth x 0.6
What are the types of fluids?
Plasma, Lymph, interstitial Fluid and cerebrospinal fluid.
What is turnover rate of plasma glucose pool?
The turnover rate of the plasma glucose pool is the rate at which glucose is being removed from and returned to the plasma, typically measured in milligrams per minute. It reflects the balance between glucose production and utilization in the body and is an important indicator of metabolic function and health. A higher turnover rate can indicate greater glucose utilization or production.

These proteins help transport glucose down its concentration gradient without using energy.

Does concentration of plasma sodium ions affect the blood osmotic pressure?
yes, the higher number of plasma sodium ions the greater the osmotic pressure.
