Answer: Add more of the proteins to the plasma membrane and measure the rate of the particle movement.

Explanation:

<u>A membrane protein is a protein molecule that is attached to or associated with the membrane of a cell or organelle.</u> Membrane proteins can be grouped into two groups based on the way they associate with the membrane.:

  • Integral membrane proteins are permanently rooted within the plasma membrane. They perform many important functions; these include the transport of molecules across the membrane.
  • Peripheral membrane proteins are proteins that are only temporarily associated with the membrane. They can be easily removed, allowing them to become involved in cellular communication.

<u>A channel protein is an embedded protein found the cell membrane which provides a hydrophilic passageway for water and small, polar ions</u>. They have a size which excludes all but the specific molecules which move from an area of high concentration to an area with a lower concentration.

To determine if the new membrane protein is a channel protein involved in membrane transport, an experiment could be made by adding more of the proteins to the plasma membrane and measure the rate of the particle movement. If the channel is involved, then the rate will be faster because there are more channels that make the movement faster.

Answer:

Explanation:The investigation is aimed at understanding

1. how molecular size affects movement through a membrane.

Therefore

2.Add more of the proteins to the plasma membrane.

Then measure the rate of the particle movement

A student is conducting their science experiment on the effect of caffeine on dogs. He has 3 groups of test subjects. The 1st gr
LekaFEV [45]

The independent variable of an experiment is the one that is intentionally changed or manipulated to see the results of changing said variable.

We are told that in each different group, the amount of caffeine that is given to the dogs changes - in the control group, they get no caffeine, in the 2nd group, they get 10 mg of caffeine each, and in the 3rd group, they get 50 mg of caffeine each.

Therefore, since the amount of caffeine that is given to the dogs is the only variable that is being manipulated, this is the independent variable.

bagirrra123 [75]

Answer:

1, 4, 5 are true. 2, 6, 7, 9 are not true. 3 and 8 are not known.

Explanation:

According to the information we have gathered from the vehicles sent to Mars and the data they collected and analyzed, "Minerals of types known to form in liquid water" on Mars. There is "abundant water ice" and also "dried-up river beds".These statements actually exist.

"Surface pools of liquid water" does not exist on Mars. "A network of straight-line canals", "cities built by an ancient civilization" and "frequent rainfall and snowfall" also do not exist on Mars according to the data.

We do not have any information to prove the existense of "underground pockets of liquid" and "microscopic life" but they are possibilities.

I hope this answer helps.

G protein‑coupled receptors (GPCRs) and receptor tyrosine kinases (RTKs) are two basic receptor types by which cells transduce s
elena-s [515]
<h2>GPCRs,RTKs</h2>

Explanation:

G Protein Coupled Receptors(GPCRs) are more common and found in almost all eukaryotes whereas Receptor Tyrosine Kinases(RTKs) are second largest family of receptors that relay signal from cell surface to the interior

  1. G protein coupled receptors(GPCRs) interacts with the ligand activated GPCR and phosphorylates its intracellular domain.This process of phosphorylation can terminate signal or desensitize receptor
  2. Autophosphorylation of receptor can initiate signal in case of Receptor Tyrosine Kinases(RTKs);Autophosphorylation is a feature of RTKs in which receptor dimerization activates intrinsic tyrosine kinase activity by which they phosphorylate its own tyrosine residue on cytosolic phase
  3. Seven transmembrane helices can be seen in case of G protein-coupled receptors(GPCRs);transmembrane protein of it consists of single polypeptide and spans the membrane 7 times
  4. Insulin receptor is a part of Insulin Signalling which comes under RTKs;Insulin receptor always exist in case of dimeric form
  5. Epinephrine receptor is an example of GPCRs;Epinephrine is an endocrine hormones produced in stress condition
  6. Transmembrane protein of GPCR activates G protein,activated G protein binds with effector enzyme and activate it;effector enzyme further can produce or destroy secondary messenger
