Answer:
most endothermic reactions
Explanation:
In endothermic reactions, the entropy of the environment decreases.
The entropy is the measure of the disorder of a specific system.
An endothermic reaction is every chemical reaction in which energy is absorbed.
In a comparison of an endodermic reaction in which energy is released in light or heat form.
Answer:
The object placed in the water has a volume of 19 cm³
Explanation:
<u>Step 1: </u>Data given
volume of the cylinder before adding the object = 28 mL = 28 cm³
After adding an object with volume X the volume rises to 47 mL = 47 cm³
<u>Step 2:</u> Calculate the volume of the object
Volume of the object = Final volume - initial volume
Volume of the object = 47 cm³ (or 47 mL) - 28 cm³ ( or 28 mL) = 19 cm³ (or 19 mL)
The object placed in the water has a volume of 19 cm³
Answer: 1. two molecules of NADH, two of ATP, and two of pyruvate
Explanation:
During glycolysis 4 molecules of ATP are synthesized by two substrate level phosphorylation (first in step 6 conversion of 1,3-Bisphospho glycerate to 3-Bisphospho glycerate by 1,3-Bisphospho glycerate kinase produces 2 molecules of ATP . Secondly 2 molecules of ATP is produced in step 9 by pyruvate kinase). But 2 molecules of ATP are used in step 1 and 3 by hexokinase and phospho fructo kinase respectively, hence a net yield of only two ATP.
2 molecules of NADH is produced in step 5 by Glyceraldehyde-3-phosphate dehydrogenase.
The end product of glycolysis is 2 molecules of pyruvate.
