What are characteristics of allosteric enzymes?
Veronika [31]

Answer:

(B) They may have binding sites for regulatory molecules that are separate from active sites.

(C) They generally have more than one subunit.

(E) They interconvert between a more active form and a less active form.

Explanation:

Allosteric enzymes are the regulatory enzymes that have a specific site for binding of modulator or effector molecule. The activity of these enzymes is altered by the noncovalent binding of modulators at the allosteric site. The binding of the modulator brings about a conformational change in the allosteric enzymes.

The relatively inactive conformation of these enzymes is called T state while the active conformation is the R state. Most of the allosteric enzymes have multiple subunits and deviate from Michaelis–Menten kinetics and exhibit a sigmoid saturation curve of V0 vs. [S].

How would cellular respiration cause a loss in mass in the organis?
Rufina [12.5K]
Cellular respiration is the process by which living organisms convert their chemical energy from nutrients into ATP. Cellular respiration is one of the major ways by which living organisms release chemical energy to drive chemical activities. Cellular respiration cause loss in dry weight. This is because, during cellular respiration there is release of energy from the living organism, carbon dioxide and oxygen are also exchanged. The energy that has to be spent during respiration is responsible for the loss in mass in living organisms.

Using the specific steps of the scientific method, tell me how you would use the scientific method to solve this problem: A fami
Nastasia [14]

Answer:

Explanation:

Scientific Research is a method used in the construction and testing of a scientific hypothesis.

It has six steps that can be used in solving questions ask or observations made which is A family wants to test the effectiveness of a misting shower head in conserving (saving) water compared to their regular shower head.

Steps to follow:

Make an observation: An observation would be made on how water is been used in the house and how it can be conserved, this observation is what brings about the question asked

Ask a question : The question is

which is more effective in conserving water a misting shower head or regular shower.

Form a hypothesis, or testable explanation: An hypothesis is formulated for the question asked

Example: Null hypothesis: Mistling shower conserves more water than shower head

Alternative: Mistling shower conserves less water that normal shower.

Make a prediction based on the hypothesis: Predictions are made on what could be the cause if there is indeed a difference and what could cause the difference

Test the prediction: An experiment is conducted to test the hypothesis if indeed Mistling is better than normal shower, the appropriate method is determined to be used for the experiment.

Iterate: The result gotten helps to butters our hypothesis if its to be acceoted or rejected. If rejected further research can be conducted on the effectiveness of normal shower in conserving water.
