1

What is Metabolism

Highly integrated and regulated network of biochemical pathways that synthesizes everything our cells need as well as producing energy to power various cell functions

2

What is a metabolic pathway

a serial chemical transformation

3

What is the name of the chemical which is changed

Intermediate or metabolite

4

How is each step processed (what is needed)

each reaction is catalyzed by a different enzyme

5

What is Catabolsim

Takes Energy-yielding nutrients (carbs, fats, proteins) and turns them into energy-poor end products (CO2, H2O, NH3)
it also creates ATP (chemical energy)

6

What is Anabolism

Takes Precursor molecules (amino acids, glucose, fatty acis, nitrogenous bases) and turns them into complex molecules (polysaccharides, lipids, proteins, nucleic acids)
Consumes ATP to work

7

What are energy-yielding nutrients

Carbs, fats and proteins

8

What are energy-poor end products

CO2, H2O and NH3 (ammonia)

9

What are the precursor molecules

Amino acids, glucose, fatty acid and Nitrogenous bases

10

What are the complex molecules

Polysaccharids, lipids, proteins and nucleic acids

11

Common pattern Representing Catabolism Stage 1: Proteins

it is broken down into amino acids

12

Common pattern Representing Catabolism Stage 1: Carbohydrates

broken down into Monosaccharides (glucose)

13

Common pattern Representing Catabolism Stage 1: Triacylglycerols (fats)

broken down into Fatty acids + glycerol

14

Simple pattern Representing Catabolism Stage 2: amino acids

broken doesn into Pyruvate and acetyl CoA

15

Simple pattern Representing Catabolism Stage 2: Fatty acids + glycerol

Pyruvate and Acetyl CoA

16

Simple pattern Representing Catabolism Stage 2: Glucose

Goes thro glycolysis using ADP and NAD+ to create ATP (small amount) and NADH which also producing Pyruvate and Acetyl CoA

17

Simple pattern Representing Catabolism Stage 3: Acetyl CoA

Enters citric acid cycle and uses NAD+ and FAD to produce NADH and FADH2 while also producing CO2

18

Simple pattern Representing Catabolism Stage 3: Oxidative Phosphorylation

Oxidative Phosphorylation uses NAD+ and FAD to produce NADH and FADH2 while also turning ADP into ATP and O2 into H2O
