Answer: Protons contribute towards making ATP by producing proton-motive force that provides energy for ATP synthesis.
Explanation: In the respiratory chain, the transfer of electrons from one complex to another is accompanied by pumping of protons out of the matrix. This creates a difference in proton concentration and separation of charge across the mitochondrial inner membrane. The electrochemical energy inherent in this difference in proton concentration called proton-motive force is used to drive ATP synthesis as protons flow back passively into the matrix through a proton pore.
There are 2 stages in photosynthesis
light stage and dark stage
light stage takes placein the grana because there's presence of chlorophyll. 2 reactions take place here.
1. photolysis of water where water molecules are split into hydrogen ions and oxygen gas in presence of chlorophyll and oxygen gas. the oxygen gas is released into the atmosphere but hydrogen ions are used in dark stage.
2. formation of adenosine triphosphate which is formed by combination of adenosine diphosphate and an inorganic phosphate in presence of light. this adenosine triphosphate is also used in dark stage
dark stage is a light independent stage which takes place in the stroma. energy is provided by adenosine triphosphate formed in the light stage. this stage involves tge combination of carbon(iv)oxide and hydrogen ions to form a simple carbohydrate and a water molecule. this process is known as carbon(iv)oxide fixation which is the reduction of carbon(iv)oxideby hydrogen ions using adenosine triphosphate energy to form a simple carbohydrate.
This simple carbohydrate is changed to glucose for use in the plant or to starch for storage
Answer:
c. When a rose bush cell divides, it copies its parts then divides into two cells <em><u>and</u></em>
d. The bacterium was formed when another bacterium divided
Explanation:
C is correct because the cells inside are part of a larger being (the rose bush), when they divide they are simply creating more cells (hence making the rose bush grow).
D is correct because bacterium are <u>unicellular</u> organisms, meaning they are themselves single cells that are organisms, unlike the rose bush consisting of many cells.
