What else can I help you with?
Oxygen is produced during the light reactions when?
Oxygen is produced during the light reactions of photosynthesis when water molecules are split by the photosystem II complex. This process releases oxygen as a byproduct.
Are the chlorophyll molecules in PSI and PSII the same?
No, the chlorophyll molecules in Photosystem I (PSI) and Photosystem II (PSII) are not the same. They differ in absorption spectra and redox properties, allowing them to play distinct roles in the light reactions of photosynthesis.
True or false an electron transport chain connects photosystem 1 and photosystem2?
False. The electron transport chain connects the two photosystems in the thylakoid membrane, but it does not directly connect photosystem 1 and photosystem 2. Instead, it shuttles electrons between the two photosystems as part of the light-dependent reactions of photosynthesis.
Where do electrons for photosystem II come from?
Electrons for photosystem II come from the splitting of water molecules during the light-dependent reactions of photosynthesis. This process, known as photolysis, occurs in the thylakoid membranes of chloroplasts. The electrons released from water molecules replace those lost by chlorophyll molecules in photosystem II, allowing the photosystem to continue the electron transport chain and ultimately produce ATP and NADPH for the Calvin cycle.
Where do electrons get their energy in photosystem I?
In photosystem I, electrons get their energy from the absorption of light by chlorophyll molecules. When light is absorbed, it excites the electrons in the chlorophyll, allowing them to move through a series of electron carriers in the photosystem to generate energy for the production of ATP and NADPH during photosynthesis.
Which is a role a photosystem 2 in the light reactions?
Splitting H2o
Which role is of photosystem ii in the light reactions?
Splitting H2O (Apex)
Which is the role of a photosystem I in the light reactions?
To make energy-carrier molecules like NADPH
What is a role of photosystem 2 in light reactions?
Photosystem two produces O2, ATP, and NADP+
How do photosystem 1 and 2 allow the calvin cycle to work?
No. Photosystems I and II are where light-dependent reactions occur, while the Calvin Cycle is where light-independent reactions occur. Photosynthesis begins with Photosystem II, then Photosystem I, then the products from there go to the Calvin Cycle. (yes photosystem II comes before photosystem I)
Which is a role of photosystem 11 in the light reactions?
Photosystem II plays a role in absorbing light energy and initiating the process of photosynthesis by passing electrons through the electron transport chain. It also splits water molecules to release oxygen as a byproduct.
Which is the rule of photosystem one in the light reactions?
Photosystem I (PSI) plays a crucial role in the light reactions of photosynthesis by absorbing light energy and facilitating the conversion of that energy into chemical potential. It primarily focuses on the reduction of NADP+ to NADPH, which is essential for the Calvin cycle. PSI works in conjunction with photosystem II (PSII) and receives electrons from the electron transport chain, ultimately contributing to the formation of ATP and NADPH, the energy carriers used in the synthesis of glucose during the light-independent reactions.
Water participates directly in the light reactions of photosynthesis by?
Water participates directly in the light reactions of photosynthesis by donating electrons to photosystem II during the process of photolysis. These electrons are used to replace the ones lost by chlorophyll when it absorbs light energy, allowing the photosystem to continue absorbing light and generating ATP and NADPH for the Calvin cycle.
How does water participate in the light reactions of photosynthesis?
Donating electrons to photosystem 2
What is the role of the plastocyanin?
Plastocyanin is a copper-containing protein that plays a crucial role in photosynthesis by shuttling electrons between photosystem II and photosystem I in the thylakoid membrane of chloroplasts. It helps in the transfer of electrons during the light-dependent reactions of photosynthesis.
Which is a role in photosystem in the light reactions?
it is the first phase. it is making NADPh and ATP.
What is the role of photosystem ll in the light reactions?
we call it calvin cycle. It is making glucose.
