Answer:
Glycolysis is the first step of the cellular respiration in an organism which is metabolic pathway that is completed in the cytosol of the cell that leads to the converting glucose to the pyruvate in order to produce energy in form of ATP:
1. Glucose-6-phosphate is ---> fructose-6-phosphate
2. fructose-6-phosphate ---> fructose-1,6-biphosphate
3. fructose-1,6-biphosphate ---> glyceraldehyde-3-phosphate(GAP) and dihydroxyacetone phosphate (DHAP).
4. GAP is oxidised ----> 3-bisphosphoglycerate + NADH
5. 3-bisphosphoglycerate ----> 1,3-bisphophoglycerat
6. 1,3-bisphophoglycerate ----> 3-phosphoglycerate
7. 3-phosphoglycerate ----> 2-phosphoglycerate
8. 2-phosphoglycerate ----> phosphoenolpyruvate (PEP)
9. phosphoenolpyruvate to ADP ----> pyruvic acid + ATP
Formation of ATP occurs in both pathways or process that are respiration and fermentation. Fermentation is a catabolic pathway leads to the degradation of sugars (partial) that result in the gain of energy and this energy are absorbed in ATP. There are difference of the amount of energy or ATP produce in these process in respiration 38 ATP are produced whereas during fermentation only 2 ATP are produced.
D. Shows how water molecules attract to the glass tube.
Answer:
The correct option is B) Outer space
Explanation:
Most of the radiations emitted by the Earth are absorbed by the Earth;s surface. These radiations cause the Earth to get warm and also causes global warming. However, little of this radiation is reflected back towards the outer space. Hence, the correct option is B.
Answer: The scientific method is cyclic.
Explanation: Scientific methods is the systematic way of using knowledge , hypothesis , observation , theories and experiments , to give us understanding for the questions.
Scientific method is always cyclic as it involves several steps. Cyclic way give us better understanding about facts and whole phenomena.
Answer:
a) properties of the molecule as a result of abnormal interactions between adjacent hemoglobin molecules
Explanation:
In sickle cell disease, for example, a nonpolar amino acid (valine) replaces a polar amino acid (glutamate). This substitution of amino acids reduces the hemoglobin’s water solubility. The mutated hemoglobin molecules form long, stiff and rod-like crystals inside red blood cells which are otherwise not formed by normal hemoglobin molecules.
These abnormal crystals of hemoglobin cause the deformation of RBCs making them sickle-shaped that cannot properly squeeze through narrow blood vessels. Therefore, the substitution of single amino acid results in abnormal interaction of two or more hemoglobin molecules that are not exhibited by normal hemoglobin molecules.
