4. respiration exam QUESTIONSThe diagram shows aerobic respiration of glucose. The numbers indicate how many
molecules of each named substance are formed or used when one molecule of glucose
is respired.
1.1 Name substance Y. - answer water (6 oxygen +...) turns into what
name stage B – answer kreb cycle
name the organelle in which stages B and C occur – answer mitochondria
How many carbon atoms are there in one molecule of pyruvate? Use evidence from the
diagram to explain your answer.
Number .......................................
Evidence - answer3;
2 pyruvate formed per (6-C) glucose (and no CO2 lost yet) /
pyruvate minus CO2 →
one pyruvate releases 3 CO2;
For each molecule of glucose, how many molecules of ATP are formed by oxidative
phosphorylation? - answer34
ATP is better than glucose as an immediate energy source for cell metabolism. Give
one reason why.
......... - answerEnergy released in a single reaction / energy (released) in small
quantities / energy (released) in manageable quantities;
Complete the flow chart by writing, in the appropriate boxes, the number of carbon
atoms in substance P and the name of substance Q. - answerP=3
Q= acetate
Some ATP is formed in the cytoplasm and some in the mitochondria. Use the
information given to calculate the number of molecules of ATP formed in a
mitochondrion from one molecule of glucose in aerobic respiration. Show how you
arrived at your answer. - answer36
2 ATP = formed in glycolysis in the cytoplasm
36 ATP = formed in the mitrochondria!!!
only in the mitrochondria = 36
The main stages in anaerobic respiration in yeast are shown in the diagram.
