Within the chloroplast, the pigments that capture solar energy are located in B_i false Metabolism Which of the following is not true regarding ATP? sugar as part chemical structure does it participate in could less energy any terminal plowshare group has been removal Most of it is made in the the cells. is used in of chemicals the plasma membrane In order for a cross-country skier to ascend and descend a hill. She he must energy stored in food to potential chemical usually composed of lipid combined with protein generally work by lowering the energy of activation for a cellular reaction must always have at least two substrates to be active. slow chemical reactions. Eire's active site does not change in shape to allow for substrate binding 4, What happens to a cell when it's placed in a Facilitated diffusion differs from simple diffusion in that facilitated diffusion moves substances from high to low concentration. true false

Explanation / Answer

10.True

The thylakoids present in the stroma contain chlorophyll which trap the energy and organize themselves to form a stack of coin like structures known as the grana.

1.B

All reactions that involve ATP are coupled reactions.

2.A.

The potential energy is converted into the kinetic energy

3 .B

Enzymes generally work by lowering the energy of activation for a cellular reaction.

4.Hypotonic solutions are the solutions are those solutions that have higher water concentrations and lower salt concentrations. (Hypos =under or less) and hence whenever a cell is placed in an hypotonic solution as the concentration of water is more outside the cell there is a net movement of the water molecules into the cell.

5.False

facilitated diffusion is active process and involves movement of molecules up the concentration gradient while simple diffusion is a passive diffusion and movement of molecules is along the concentration gradient
