Distal water molecules play a critical role in enzymatic reactions by stabilizing the protein structure, facilitating substrate binding, and participating in the proton transfer process. They help create an optimal microenvironment for catalysis within the enzyme's active site.
What else can I help you with?
Is the stomach distal to the heart?
The heart is SUPERIOR to the stomach...ABOVE... Distal usually only applies to the appendages, or limbs. The hand is distal to the elbow. The foot is distal to the ankle. Distal might give you partial credit for some answers but when you are dealing with the torso you will want to use SUPERIOR or INFERIOR.
What regulates water reabsorption in the distal convoluted tubules?
The hormone aldosterone regulates water reabsorption in the distal convoluted tubules. It works by increasing the reabsorption of sodium ions, which in turn triggers the reabsorption of water from the tubules back into the bloodstream.
Is the distal tubule and collecting ducts relatively impermeable due to water in the absence of hormones?
No, the distal tubule and collecting ducts are not impermeable to water in the absence of hormones. These segments of the nephron regulate water reabsorption based on hormonal signals, particularly antidiuretic hormone (ADH). When ADH is present, water channels called aquaporins are inserted into the tubule walls, allowing for increased water reabsorption.
Is the distal convoluted tubule more permeable to water than solutes?
No, The DCT is impermeable to water. Solutes (Na and Cl) are absorbed from the DCT. As a consequence the osmolality of tubular fluid DECREASES as it moves through the distal convoluted tubule, from ~100mOsm/L at it exits the ascending limb of the loop of Henle to around 70mOsm/L as it enters the collecting duct.
The hormone ADH functions to promote water re-abdsorption through the wall of what in the kidney?
ADH promotes water reabsorption through the wall of the collecting duct in the kidney by increasing the permeability of the duct to water. This helps regulate water balance in the body by allowing the reabsorption of water into the bloodstream.
What would an EMT use a distal pulse for?
To check for blood flow distal from an injury.
Is the stomach distal to the heart?

Is the knee distal or proximal from the ankle?
It is never looked at this way. We always use the point of attachment of the limb as the starting point. The ankle is distal from the knee. No one would use it any other way.
Is the distal tubule and collecting ducts relatively impermeable due to water in the absence of hormones?
No, the distal tubule and collecting ducts are not impermeable to water in the absence of hormones. These segments of the nephron regulate water reabsorption based on hormonal signals, particularly antidiuretic hormone (ADH). When ADH is present, water channels called aquaporins are inserted into the tubule walls, allowing for increased water reabsorption.
Is the heart distal to the rib cage?
The heart is SUPERIOR to the stomach...ABOVE... Distal usually only applies to the appendages, or limbs. The hand is distal to the elbow. The foot is distal to the ankle. Distal might give you partial credit for some answers but when you are dealing with the torso you will want to use SUPERIOR or INFERIOR.

What is the opposite of distal?
Proximal is the opposite of distal.
Is the foot distal or proximal to the heart?
Distal
What is the distal anterior wall in the heart?
Distal and anterior are adjectives that anatomists use to describe locations of various organs and tissues. Distal - meaning "far from" Anterior - meaning "in front" Thus, if we were using the top of the heart as a reference point, the distal anterior wall in the heart would be the part of the heart wall that is distal (since we said the top of the heart was our reference, it would have to be at the bottom of the heart) and anterior (which would be the front of the heart).
What are the processes of distal tubule?
This is in the kidney and it mainly controls how much or little water is kept in the body
Anti duretic hormone increases absorption of?
It increase the reabsorption of water. That is from distal convaluted tubules
