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)
Increasing the intensity of light decreases the rate of photosynthesis true or false?
false
True or false Photosynthesis and cellular respiration form a cycle that links organisms to each other and to their environment?
false, photosynthesis occurs in plants only
Are ATP molecules made during the light-independent reactions of photosynthesis?
An electron transport chain is gone through when electrons are transferred from photosystem 1 to photosystem 2. ETC pumps protons through the thykaloid. Protons are diffused out of the thykaloid and through the ATP synthase.
True or false the reactions that convert the energy in sunlight into chemical energy of ATP and NADPH are called the Calvin cycle?
FALSE, it is light reactions. Just took a test with this exact question on it.
Light energy is trapped and converted into chemical energy during the citric acid cycle true or false?
False. It's during photosynthesis
During the dark reactions the reaction center splits water?
No, during the light reactions. Photolysis splits the water molecule at Photosystem II.
True or false During photosynthesis carbon dioxide and water in the presence of light are used to form sugars and oxygen gas?
False.
In cells endergonic reactions are often coupled with enzymatic reactions that store energy True or false?
false
Do all pants carry out photosynthesis true or false?
False, because only green plants carry out photosynthesis. Non-green plants do not carry out photosynthesis.
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)
The dark reactions occur within the thylakoid membranes true or false?
False. False.
Increasing the intensity of light decreases the rate of photosynthesis true or false?
false
Does one important sugar results from photosynthesis is cellulose?
false
Are thylakoid membranes the site of the light reactions?
Photosynthesis takes place in the chloroplast, which is also where the thylakoid discs are located.
True or false During photosynthesis when electrons are transferred from one molecule to another they are usually carried by hydrogen ions and NADP plus?
True
Does some rotifers reproduce sexually only during harsh climatic conditions true or false?
A) true
