In an energy absorbing reaction, the energy of the products is greater than the energy of the reactants. In an energy releasing reaction, the energy of the reactants is greater than the energy of the products.
Question: Describe how a single amino acid substitution causes hemoglobin molecules to stick together. Use what you know about the structure of Hb and HbS, the properties of glutamic acid and valine, and how hydrophobicity causes molecules to behave in water.
Answer:
A Single amino acid must be polar to attract, just like water.
Explanation:
Sickle cell is an genetic illness and it is began by a alteration that arises in the beta sub units of the haemoglobin. Haemoglobin is a tetrameric protein made up of 2 alpha sub units and 2 beta sub units and it is the important part of the blood accountable for oxygen passage. Sickle cell is a illness that consequences from a replacement of a polar amino acid identified as glutamate with a non polar one valine at site six of the beta polypeptide component of haemoglobin. The replacement occurs as a consequence of a alteration in one of the bases in the beta-globin gene from adenine to thymine . As a outcome of this change, the beta polypeptide chains convert sticky in low oxygen circumstances since the valine sticks out of the chain and interrelates with neighboring non-polar amino acids.
Answer:
43 monosaccharides will be joined together to make the complex carbohydrate.
Explanation:
The complex carbohydrates are synthesized by the joining of monosaccharide residues by glycosidic linkages.One glycosidic linkage joins two monosaccharide residues by the elimination of one molecule of water.
In other words it can be said that elimination of one water molecule joins two monosaccharides.By the same way elimination of 42 molecules of water will result in the joining of 43 monosaccaride residues.
To assess the CPR quality, once the tube has been inserted
by one of your members, one should continue chest compressions so that it will
help the patient to breathe and a way of giving assistance to the heart. The
waveform in the capnogrophy screen should be assessed and to find out whether
the CPR is working.
Fog is cause by water vapor in the air so if it’s a dry day then there will be no fog in sight.However, on damp days fog is most likely something you can expect
