What occurs in the light dependent step of photosynthesis?

• Plants convert carbon dioxide into glucose using ATP and NADPH

• Plants convert oxygen into water using hydrogen ions and electrons

• Light energy is converted into chemical energy by splitting water and creating NADPH and ATP molecules

• Light energy is absorbed by the pigment caritanoid within the chloroplasts

What is the effect of increasing the concentration of reactants on the rate of a chemical reaction?

• It decreases the rate

• It increases the rate

• It has no effect

• It stops the reaction

Which of the following is a balanced chemical equation for the reaction between hydrogen and oxygen to form water?

Tags

NGSS.MS-PS1-5

• Decomposition

• Synthesis

• Single replacement

• Double replacement

What occurs in the light independent step of photosynthesis

• ADP and NADP are converted into ATP and NADPH

• Light is needed to split water into oxygen, hydrogen ions and electrons

• Light energy is absorbed by chlorophyll in the chloroplasts to create ATP

• ATP and NADPH from step one are used to build glucose from carbon dioxide
