water) is -25.5 kJ/mole. what is overall change in free energy to
add a P to X using ATP
+56

44.
The biosynthesis of ATP from ADP and a phosphate group donated
by a metabolic intermediate is called
A.
oxidative phosphorylation
B.
photophosphorylation
C.
anaplerotic reaction
D.
substrate-level phosphorylation
46.
The following is incorrect regarding the statement "A small
amount of ATP is made in glycolysis."
A.
Enzymes producing ATP from ADP + Pi, coupled with ΔGo < 0
reactions, are called kinases.
B.
Substrate-level phosphorylation depends on a ΔpH and a voltage
gradient.
C.
ATP is formed by phosphoglycerate...
A mitochondrial membrane complex consisting of ATP synthase,
adenine nucleotide translocase (ATP-ADP translocase), and phosphate
translocase functions in oxidative phosphorylation. Adenine
nucleotide translocase, an antiporter located in the inner
mitochondrial membrane, moves ADP into the matrix and ATP out.
Phosphate translocase is also located in the inner mitochondrial
membrane. It transports H ions and phosphate (H2PO4–) ions into the
matrix.
Explain in detail how fatty acid molecules enter the matrix of
mitochondria of hepatocyte cells and what happens to them in the
mitochondrial matrix.
can u tell me please its a 15 marks question
Compare the ATP yield of three glucose molecules that enter
glycolysis and are converted to pyruvate with that of three glucose
molecules that proceed through the pentose phosphate pathway such
that their carbon skeletons (as two F6P and one GAP) reenter
glycolysis and are metabolized to pyruvate. Indicate the steps
where ATP was used or produced and the overall ATP totals.

1. Creatine phosphate:( Choose the correct answer)
A. Enters the mitochondria for aerobic production of ATP
B.Generates ATP quickly, but the quantity is limited
C. Is a form of energy that is usable by the body
D. Generates the majority of ATP in muscle contractions
2. Ways to decrease the risk food allergies in children include
all of the following except:( Choose the correct answer)
A. Avoidance of common allergens such as fish,eggs, and peanuts
during pregnancy
B. Introduction of...
The reaction glucose + ATP <=> glucose-1-phosphate + ADP
has ΔG°' = -9.6 kJ mol-1. This is a coupled reaction which can be
broken into two parts. The first part of the reaction is ATP + H2O
<=> ADP + Pi, with ΔG°' = -30.5 kJ mol-1. The second part of
the reaction is glucose + Pi <=> glucose-1-phosphate + H2O.
Calculate the ΔG°' value for this reaction in kJ mol-1.
How many gross and net molecules of ATP will one get from
complete oxidation of a saturated fatty acid that has 18 carbons?
Please show all the detailed steps (which step of aerobic
respiration) and calculations that you will be doing to arrive at
your answer to get full credit. I need to see the energy balance
sheet for each step, involved in this oxidation (check the energy
balance sheet for glucose in text book to get idea of how...
