PHOTOSYNTHESIS

Which organelle is responsible making food (Glucose) using sunlight?

• Cell Membrane

• Nucleus

• Chloroplast

• Mitochondria

What is the pigment in chloroplasts that performs photosynthesis?

• Chlorosynthesis

• Chlorophyll

• Chloroplast

• Green

Where does dark reaction or light independent specifically occur?

• thylakoid membrane

• Stroma of the chloroplast

• Grana

• nuclear membrane

Where does light dependent specifically occur?

• thylakoid membrane of the grana

• Stroma of the chloroplast

• mitochondria

• nuclear membrane

•An enzyme that fixes carbon from atmosphere to convert it to complex macromolecule glucose.

• RuBP (Ribulose bisphosphate)

• RuBisCo (Ribulose Bisphosphate Carboxylase)

• PGA (3-Phosphoglycerate)

• G3P (Glyceraldeyhyde 3-Phosphate)

•Plants and plant-like organisms make their own food or energy (glucose) from sunlight.

• Chemotrophs

• Heterotrophs

• Autotrophs

• Saprophytes

 

Energy and Oxygen are created from visible sunlight during the

• Light independent reaction

• Light dependent reaction

• Calvin Cycle

• Krebs Cycle

What does light do when it strikes the chlorophyll molecules of photosystems I & II

• Light causes glucose to be synthesized directly inside the chlorophyll of the photosystems

• Light causes the conversion of water into carbon dioxide

• Light directly causes carbon dioxide to attach to RuBP during the carbon fixation stage of the Calvin Cycle

• Light causes electrons to get excited (gain energy) and travel down an electron transport chain embedded in the thylakoid membrane

After light excites electrons and they leave Photosystem II down the first electron transport chain. How are these electrons replaced by Photosystem II?

• Oxygen is reduced and the electrons are given to the chlorophyll molecules of photosystem II

• Water is split, and the electrons are given to the chlorophyll molecules of photosystem II

• Carbon dioxide is split, and the electrons are given to the chlorophyll molecules of photosystem II

• Hydrogen undergoes fusion, and the electrons are given to the chlorophyll molecules of photosystem II.

The splitting of water at the photosystem II is known as ________ and results in the production of _________.

• Photosynthesis; carbon dioxide, G3P, and electrons that are given to the photosystem

• The Calvin Cycle: Carbon dioxide, G3P, and electrons that are given to the photosystem

• Chemiosmosis: oxygen, hydrogen ions (protons), glucose, and electrons that are given to photosystems II.

• Photolysis: oxygen, hydrogen ions (protons), and electrons that are given to photosystems II.
