Dna proofreading. DNA excision repair. The rezponsible enzyme (d)
Remember that CO2, light and heat (to activate the reaction and keep the enzymes happy) are all needed for a reaction. When one goes missing, it destroys the whole process.
1. No light = no reaction can be made. That means the plant wouldn't intake any CO2 anyway.
2. When very hot the enzymes will denature (plant dead) or when cold, the activation energy will not be there. So once again, it will not respond to light as it is not its primary concern.
Answer:
Organic compounds contain carbon and hydrogen (which may be replaced by other atoms).
Active Transport: Moves molecules and ions from lower concentration to higher concentration w/ ATP energy
Passive Transport: Move molecules and ions from higher concentration to lower concentration w/o any energy
Hope this helped!
Non polar molecule move across a membrane through simple diffusion, when moving up their concentration gradient. Simple diffusion involves movement of molecules through a membrane without the help of integral membrane protein. These molecules are driven by the force of diffusion. This is different from facilitated diffusion where molecules only move with the aid of integral protein in the membrane.
