cellular respiration (lecture 6)

Question 1

what four functions of plant & animal cells require lots of energy? (mmmm)

Answer 1

Mechanical work, Make new Proteins, Movement of molecules across membranes, Maintain order

Question 2

What part of the cell is the site for cellular respiration

Answer 2

the Mitochondrion of the cell (which is the organelle where most chemical energy is converted into useable energy - ATP)

Question 3

What structural features of the mitochondrion are integral for cellular respiration?

Answer 3

Two membranes - Inner and Outer & Two compartments - The Matrix and the Inter-membrane space

Question 4

What does the inter-membrane space allow for

Answer 4

creating the proton gradient needed for ATP synthesis

Question 5

Describe the sequence of cellular respiration

Answer 5

Begins with glycolysis, then pyruvate oxidation and citric acid cycle, then oxidative phosphorylation (electron transport and chemiosmosis)

Question 6

Summarise the purpose of cellular respiration

Answer 6

Conversion of chemical energy within the mitochondria to produce and synthesis ATP, the main energy carrier of the cell (as well as carbon dioxide and water) from glucose and oxygen

Question 7

what is ATP

Answer 7

Adenosine Triphosphate is an energy carrier that powers cellular activity by releasing energy in a controlled manner and regenerates itself for the continued support for essential (animal and plant) cell processes

Question 8

where is the most ATP produced

Answer 8

during oxidative phosphorylation the most ATP is synthesised, but the ATP synthase protein and high energy electrons are required to do so
