Question

If a plant ran short of carbon dioxide (CO2), which of the following would most likely be affected FIRST?

The light-independent reactions of photosynthesis

The ATP synthase within the chloroplasts

The light reactions of photosynthesis

The thylakoids within the chloroplasts

Answer 1

the first one

Answer 2

I'm not sure @ujjwal can u help with this question?

Answer 3

Sorry guys! you can ask me anything in physics and maths but biology... I even can't define cell in biology. @physicsme would be of great help. He is a biology student with a "physics" in his name.

Answer 4

thank you

Answer 5

Carbon dioxide is the fixed to sugars (carbohydrates) during the light independent reactions of photosynthesis, the process is called the Calvin Cycle.
In the light dependent reactions, the photolysis of water takes place and hydrogen ions and energy are released that are used to fix CO2 during the light independent reactions.
The ATP synthase occurs in the chloroplasts. The H+ ions move across the inner membrane in the chloroplasts.
As far as thylakoids are involved, they are the site for the light dependent reactions.

Answer 6

so... was I right?

Answer 7

from what I wrote, it's pretty obvious :)

Answer 8

even i can see that.
