Chpt 8 -Metabloism

Front 1

What is metabolism?

Back 1

All chemical & physical working of a cell.

Front 2

• Metabolism of Microbes:
• 2 types of chemical reactions.

Back 2

• Catabolism
• Anabolism

Front 3

Catabolism

Back 3

• breaks the bonds of larger molecules forming smaller

molecules

• releases energy

Front 4

Anabolism

Back 4

• biosynthesis

• process that forms larger macromolecules from

smaller molecules

• requires energy input

Front 5

What are the major metabolic functions of cells:

Back 5

• Enzymes serve as catalysis for catabolic & anabolic activities
• Cells acquire energy from an external source nutrients or the sun
• Cells extract the energy and transfer it to high energy
• molecules of ATP – via catabolic pathways
• Cells use ATP to power anabolic processes building of larger molecules and cell structures with greater complexity

Front 6

Enzymes

Back 6

Catalyst that speeds up chemical reaction by lowering energy of activation.

Front 7

Energy of Activation:

Back 7

The resistance to a reaction.

Front 8

Simple Enzyme

Back 8

consists of protein alone

Front 9

Conjugated Enzyme/ Holoenzyme

Back 9

contain protein non protein molecules
