C7 Chemical Reactions (Combined Science)

Here are some key terms for this topic: Key Terms C7

GCSE Bitesize has revision pages (that take you through the topic), a test and an activity – click on Rates of Reaction.  GCSE s-cool – Rates of Reaction – revision notes & animations, practise exam questions and a revision summary. Skoool Chemistry – click on ‘6. Rates of Reaction’ for excellent lessons that take you through the topic; also a glossary of key terms.

Chemactive worksheets and answers just click on ‘Rates questions’.

For Doc Brown’s Chemistry quizzes, word-fills, crosswords and study notes go here and just scroll down.

This is a great power-point that also revises C6 Energy changes in chemical reactions:

Chemical reactions from Carole Paquette

C71.1 RATE OF REACTION

Rate of reaction chemical kinetics (condensed) from jslayer

Science Bank (Reactions & Energy Changes): part 2 Reaction Rates (from 4m 40s) & part 3 Catalysts (from 9m 20s):

Five minutes on how to speed up chemical reactions (and get a date) from TED-Ed.

GCSE Bitesize – two videos – Rates of Reaction (3m 18s) or Rates of Reactions (4m 40s) & Bitesize Top 20 Science Demos – Rates of Reaction (5m 51s).

C7.2 REDOX

IGCSE Chemistry, a 25m lesson from ChemistryKlipz covers redox rcts (to 6m 20s):

BBC Short Circuit Redox Changes a 19m video.

8.2 Cell Respiration

IB 2.8 & 8.2 Cell Respiration Part 1, a 12m video lesson from Dan Rott and IB 2.8 & 8.2 – Respiration Part 2 (7m).

3 video lessons from Alex Lee: Electron Tomography of Mitochondria (2m 33s); Phosphorylation (4m 13s) and Chemiosmotic Theory Paradigm Shift (3m 53s)

8.1 Cell Respiration essay qus

Paul Andersen covers the processes of aerobic and anaerobic Cellular Respiration in a 14m 14s tutorial and here is Hank Green’s Crash Course Biology #7: ATP & Respiration:

An excellent 6m overview of Cellular Respiration (Glycolysis, Krebs cycle, Electron Transport).

GLYCOLYSIS

A fantastic animated tutorial from McGraw Hill Education on how glycolysis works. Wiley also have an Interactive Animation  – just click on ‘Glycolysis

Steps of Glycolysis Reactions Explained in 5 minutes and in more detail than we need but it is very good. and here Mr W sings the Glycolysis! rap. Glycolysis Pathway Made Simple !! a 6m biochemistry lecture.

KREB’S (TCA) CYCLE

Here are some fantastic animated tutorials from McGraw Hill Education – how the Krebs cycle works. Wiley also have an Interactive Animation  – just click on ‘Citric Acid Cycle’.

Mr W sings the Kreb’s! rap. A very detailed lesson on HOW TO LEARN KREB’S CYCLE in 17m.

ETC, CHEMIOSMOSIS & ATP SYNTHASE

Short, simple animations to show mitochondrial electron transport, ATP synthase & ATP synthase mechanism

Here are some fantastic animated tutorials from McGraw Hill Education – how NAD+ works, the ETC & ATP synthase & proton pump & ATP synthase. Wiley also have an Interactive Animation  – just click on ‘Oxidative Phosphorylation’.

Powering the Cell: Mitochondria, a 2m 9s visual treat from Harvard University; and here is part of it with narration. Mr W sings the ETC rap (badly!).
