1. The Nucleus contains the DNA code for the amino acid sequence (2) 3. The Nucleolus makes rRNA (4) 5. The Ribosomes translate mRna in protein synthesis 6. The endoplasmic reticulum allows for the tra...

Anaerobic respiration happens when there isn't enough Oxygen available for Oxidative Phosphorylation to occur. Without Oxidative Phosphorylation, ATP synthesis occuring across the inner mitochondrial memb...

Eukaryotes, including animal and plant cells, are characterised by their membrane nucleus. They contain organelles such as mitochondria, which are located in the cytoplasm bound by membranes. Eukayotic ce...

A neurone which is not conducting a nerve impulse has a negative charge of -70mV compared to the outside environment; there is a potential difference across the membrane. This is partly caused by movement...
