The equation for photosynthesis is carbon dioxide + water → glucose + oxygen, in the presence of light. The The Photosynthesis Equation and Chemical Symbols notes cover this in full.
In muscles, anaerobic respiration is glucose → lactic acid. The Anaerobic Respiration and Fermentation notes cover this in full.
The word equation for photosynthesis is carbon dioxide + water → glucose + oxygen, with light energy needed for the reaction. The The Photosynthesis Equation and Chemical Symbols notes cover this in full.
Magnification is calculated with magnification = image size ÷ real size. The Magnification Calculations notes cover this in full.
The word equation for aerobic respiration is glucose + oxygen → carbon dioxide + water + energy. The Aerobic Respiration notes cover this in full.
An enzyme is a biological catalyst that speeds up specific chemical reactions in living organisms by lowering the activation energy required. The The digestive system and enzymes notes cover this in full.
The cytoplasm is a jelly-like substance where chemical reactions take place and in which organelles are suspended. The Comparing Animal and Plant Cell Structures notes cover this in full.
A tissue is a group of cells with similar structure and function working together to perform a specific task. The From Cells to Organisms notes cover this in full.
