Flashcards in Bioenergetics Deck (11):
1

What is bioenergetics?

How cells produce and use energy

2

Roles of bioenergetics

General manager - thermodynamics
Process engineer - biochemistry - maya olive pathways and networks
Control engineer - enzyme kinetics - regulation and signalling

3

First law of thermodynamics

Energy can neither be created or destroyed, it is simply conserved

4

Second law of thermodynamics

Every energy transfer increases the entropy of the universe - an organism loses some of its energy to the environment

5

What is the free energy of the system?

Is the portion of the system's energy that can perform work

6

In an exergonic reaction, is energy released or required?

Released

7

In an endergonic reaction, is energy released or required?

Energy is required

8

What does ATP stand for?

Adenosine Triphosphate

9

Where is the chemical energy in ATP stored?

The last phosphate group

10

What are the two steps of ATP formation?

1) substrate level phosphorylation
2) oxidative phosphorylation

11

What does NADH stand for?

Nicotinamide adenine dinucleotide
