The dark blue color of the fishball could be due to a reaction with certain proteins or additives present in the fishball, potentially interacting with iodine or other reagents. It's also possible that the fishball contains ingredients like seaweed or specific spices that can cause a color change. Additionally, if the fishball was exposed to high heat or certain chemicals, this could lead to a change in color without the presence of starch.
they are turned into starch which is not soluble in water.
First, the plant undergoes photosynthesis, as normal. Once the glucose is produced, it is turned into starch through a process called polymerization. This happens in the organelle known as the amyloplast. Once the amyloplast has turned the glucose into starch, it moves the starch to the stroma, which is the sponge-like material that gives support to the plant cell. The starch is stored here, until the plant needs the energy, at which point the starch gets turned back into glucose and is used to provide energy to the plant.
When glucose, made in photosynthesis, is turned into an insoluble compound, it is stored as starch in plants. Starch is a polysaccharide composed of glucose units linked together in a way that makes it insoluble in water and suitable for long-term storage of energy.
It doesn't ---------------------------------------- Not sure where that guy ^ got his information, but in Biology 11 you learn that it DOES. Starch is turned to glucose during chemical digestion, and it begins in the mouth. ---------------------------------------- I'm in year 9 and I know that!
yesssssssssss definatly because crisps are made from potatos and potatos contain starch plus we havetested it with iodine andit turned blue so it does have starch
when starch is digested it gets broken up and turned into glucose (sugar). This happens so it can get to the blood stream as starch is too big as a particle to get through the walls of your veins. As glucose particles are smaller, it easier to get through.
The dark color change upon adding iodine suggests that the solution contained starch, as iodine is commonly used to test for its presence. Neither lipids nor DNA would typically cause a dark color change with iodine. Instead, lipids may remain unreactive, and DNA would require different reagents for detection. Therefore, the correct interpretation of the color change is related to starch, not the options provided.
does not matter once the Powder has starch it turns black and the powder can be any color
Lipids can store much energy.Excess starch are turned into lipids and stored.
The leaf turned blue-black in the starch test because iodine forms a complex with starch molecules, resulting in the blue-black color change. This color change indicates the presence of starch in the leaf tissue.

It has to be turned into a sugar, such as sucrose.
