Answer:d.are eventually replaced by electrons from photosytem 11
Explanation:there are two photosystems in the photosynthetic process.PSI and PS II. PS I has a reaction center called P700 because it's chlorophyll has a maximum absorption of 700nm wavelength.PSII has a reaction center called P680nm for similar reason.when an excited electron is transferred to P700,it becomes excited.this electron is passed down from from acceptor to another, until it is used to reduce NADP+ to NADPH.this electron is replaced when P680 gets excited by a photo of light and splits water to release electrons , protons and Oxygen
Answer:
Organization and effectiveness of cellular tasks
Explanation:
Cell is the fundamental unit of all living organisms where all biochemical processes responsible for the functioning of the living organism occurs. However, each cell is made up of smaller compartments or areas that run a specific biochemical process called ORGANELLES.
An organelle can be likened to a section of a house, where different activities are conducted. This enables the cellular processes to be organized and effective due to the fact that each organelle/compartment has its own specific task. The work/processes that are key to the survival of an organism are specifically allocated to organelles in a cell. For example, ribosomes conduct protein synthesis, mitochondrion performs energy production etc.
In a nutshell, this small areas or organelles in the cell makes the biochemical process easy, organized and effective.
