Dettagli

I satelliti di scienze naturali

I volumi della collana I satelliti di scienze naturali sviluppano e approfondiscono gli argomenti suggeriti nelle Linee guida per il quinto anno dei Licei, affrontandoli in un'ottica globale e sistemica.

Per un apprendimento ricorsivo

Gli argomenti sono presentati tenendo sempre conto del precedente percorso di formazione dello studente, avendo cura di richiamare i concetti indispensabili per la comprensione dei nuovi contenuti, ma anche di aprire alla conoscenza delle ricerche scientifiche "di frontiera" e dell'impatto che esse provocano sulla società e sulla cultura di oggi.

I CLIL di scienze naturali

Nei CLIL di scienze naturali i contenuti in lingua inglese sono segmentati per facilitarne la comprensione e accompagnati da numerose e diverse tipologie di esercizi che favoriscono l'apprendimento di specifiche competenze linguistiche e disciplinari.

chapter 1 and metabolism

1.1 Enzymes: the biologic catalyzers for excellence

BEFORE READING

WHILE READING

Several cellular reactions are by themselves too slow

How were enzymes discovered?

Enzymes specifically accelerate fundamental cellularreactions

Enzymes are classified based on the reactions they catalyze

Enzymes are characterized by specific properties

AFTER READING

1.2 How do enzymes act: mechanisms of activity and regulation

BEFORE READING

WHILE READING

Enzymes act by creating a complex with the substrate

Some enzymes need additional chemical compounds

Enzymes activity is affected by several parameters

Some organisms tolerate particular temperatures and pH

Enzymes are strictly regulated

AFTER READING

1.3 Metabolism at the basis of cells life and regulation

BEFORE READING

WHILE READING

Life is an unstoppable phenomenon

Metabolic pathways: sequences of reactions

Metabolic pathways: degradation and biosynthesis

Metabolism is strictly regulated

Metabolism regulation: negative feedback

AFTER READING

1.4 ATP and redox: two key points of energetic metabolism

BEFORE READING

WHILE READING

ATP: the "engine" of cell reactions

ATP hydrolysis links exergonic and endergonic reactions

Redox are paired reactions

AFTER READING

Final test chapter 1

chapter 2 The energetic metabolism of carbohydrates

2.1 Glucose degradation and biosynthesis

BEFORE READING

WHILE READING

Glucose and the energetic metabolism

Glycolysis: two phases in cells cytoplasm

Glucose may also need to be resynthetized:gluconeogenesis

AFTER READING

2.2 Cell respiration: Krebs cycle and oxidative phosphorylation

BEFORE READING

WHILE READING

Pyruvate destiny: the Krebs cycle

Oxidative phosphorylation

ATP synthetase is responsible of the production of ATP

AFTER READING

2.3 Pyruvate destiny in anaerobic conditions

BEFORE READING

WHILE READING

Fermentation produces energy in absence of oxygen

Lactic fermentation

Alcoholic fermentation

Current use of fermentations

AFTER READING

2.4 Glucose metabolism regulation

BEFORE READING

WHILE READING

Glucose catabolism is strictly regulated

Organisms control glucose metabolism in different ways

Glycolysis and gluconeogenesis are reciprocally controlled

Glycolysis regulation

Gluconeogenesis regulation

AFTER READING

Final test chapter 2

chapter 3

Plants and metabolism

3.1 Energy from the Sun: photosynthesis

BEFORE READING

WHILE READING

Heterotrophs, autotrophs and photoautotrophs

Photosynthesis represents the exact inverse of cellular

respiration

Photosynthesis can be divided into phases

Chlorophyll and the other pigments

AFTER READING

3.2 Photophosphorylation: from sunlight to chemical energy

BEFORE READING

WHILE READING

Chlorophylls are excited

The two photosystems act together

AFTER READING

3.3 The Calvin cycle

BEFORE READING

WHILE READING

Photorespiration yields carbohydrates from carbon dioxide

Calvin cycle is divided into three phases

G3P can be subjected to different destinies

AFTER READING

Final test chapter 3
