Passive transport is a movement ofbiochemicals and other atomic or molecularsubstances across cell membranes without need of energy input. Unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy. The rate of passive transport depends on thepermeability of the cell membrane, which, in turn, depends on the organization and characteristics of the membrane lipids andproteins. The four main kinds of passive transport are simple diffusion, facilitated diffusion, filtration and osmosis.
Number 3 and 4 are the correct answers hope this helped
They do this real fancy thing called breathing. There's a couple other organisms that do this too, but none compare to the frog
Positive control is Ginger root (should indicate the presence of amylase)
Negative control is Cellulose (should not contain amylase)
Here the presence of amylase is tested by testing the presence of starch using an IKI solution. Saliva is included in this experiment because it contains the enzyme amylase.
The web energy gain in fermentation is 2 ATP molecules<span>/glucose molecule. In both lactic acid and alcoholic fermentation, all the NADH produced in glycolysis is consumed in fermentation, so there is no web NADH production,
