Chloroplasts are the organelles in plant cells where photosynthesis occurs. These organelles are roughly 2 - 10 μm in diameter (they are larger than mitochondria) Each chloroplast is surrounded by a double-membrane envelope. Each of the envelope membranes is a phospholipid bilayer. WebConcentration of yeast solution (enzyme) – When there is an abundance of substrate, the more enzyme there is available, the faster the rate of the reaction will be as it would be more likely for an enzyme molecule to collide with a substrate molecule at the correct angle and with sufficient force for a reaction to occur. how many were killed in ww2
