Front (Question)

Why is glucose not a good immediate energy source for a cell?

Back (Answer)

• Stable so energy is released slowly. • Large amount of energy released - difficult to manage. • Many reactions required to release energy.

Front (Question)

If an inorganic phosphate molecule is added to ADP from a donor molecule we call this…

Back (Answer)

Substrate-Level Phosphorylation

Front (Question)

What is the equation for respiration?

Back (Answer)

Glucose + Oxygen –> Carbon Dioxide + Water + Energy (ATP)

Front (Question)

ATP + Water –> ?

Back (Answer)

ATP + Water –> ADP + Pi + Energy

Front (Question)

ADP + Pi + Energy –> ?

Back (Answer)

ADP + Pi + Energy –> ATP + Water

Front (Question)

Which enzyme is required to catalyse the hydrolysis of ATP?

Back (Answer)

ATP Hydrolase (ATPase)

Front (Question)

What is the function of Adenosine Triphosphate (ATP)?

Back (Answer)

To provide the energy to carry out processes in cells.

Front (Question)

Describe the bond that holds the outer phosphate group on an ATP molecule.

Back (Answer)

Weak Unstable Easily broken

Front (Question)

When a inorganic phosphate molecule is added to another molecule we call it…

Back (Answer)

phosphorylation

#10

Front (Question)

What are the components of an ATP nucleotide?

Back (Answer)

Adenine Ribose 3 Phosphates

#11

Front (Question)

If an inorganic phosphate molecule is added to ADP during respiration we call this…

Back (Answer)

Oxidative Phosphorylation

#12

Front (Question)

What type of reaction is: ATP + Water –> ADP + Pi + Energy

Back (Answer)

Hydrolysis Reaction

#13

Front (Question)

What are the components of an ADP nucleotide?

Back (Answer)

Adenine Ribose 2 Phosphates

#14

Front (Question)

Where is the energy in ATP released from?

Back (Answer)

The bonds between phosphate molecules

#15

Front (Question)

What does AMP stand for?

Back (Answer)

Adenosine Monophosphate

#16

Front (Question)

What does ATP stand for?

Back (Answer)

Adenosine Triphosphate

#17

Front (Question)

How is ATP suited to its function as an immediate source of energy for a cell?

Back (Answer)

• It’s instability means energy can be released quickly. • ATP is rapidly reformed from ADP. • Small amount of energy released so easy to manage. • Only a single hydrolysis reaction tak place for energy release.

#18

Front (Question)

Energy from respiration takes the form of what?

Back (Answer)

Adenosine Triphosphate (ATP)

#19

Front (Question)

What does ADP stand for?

Back (Answer)

Adenosine Diphosphate

#20

Front (Question)

Can ATP be stored in the body?

Back (Answer)

No - it is rapidly used so the body must constantly reform it.

#21

Front (Question)

If an inorganic phosphate molecule is added to ADP during photosynthesis we call this…

Back (Answer)

Photophosphorylation

#22

Front (Question)

What type of reaction is: ADP + Pi + Energy –> ATP + Water

Back (Answer)

Condensation Reaction

#23

Front (Question)

Which energy requiring process does the body use ATP for?

Back (Answer)

• Metabolic processes - making polypeptides form amino acids. • Movement - muscle contraction. • Active Transport - changing the shape of carrier proteins in cell membranes to move molecules against concentration gradients. • Secretion - to form lysosomes so cells can secrete. • Activation of Molecules - Phosphates from ATP can be used to phosphorylate other molecules to activate them.

#24

Front (Question)

Which enzyme is required to catalyse the condensation reaction of ADP + Inorganic phosphate into ATP?

Back (Answer)

ATP Synthase
