I believe that the answer to your question would be A. Heart Begins.
Answer:
The cytochrome b6f is a large multi-subunit protein, which accepts electrons from the plastohydroquinone.
One electron moves linearly toward plastocyanin while the other goes through a cyclic process, which effectively pumps more protons into the thylakoid lumen.
Explanation:
The cytochrome b6f is distributed among both grana and stroma thylakoids equally. They are usually large and embedded in the membrane.
Answer and explanation;
Nucleus; houses a cell's DNA and its processes include protein, replication and packaging for cell division. It is also the site for transcription.
Cytosol; coordinates a responsible to the environment, metabolism and motor proteins.
Endomembrane system; includes the nuclear envelope (surrounds nucleus), rough and smooth ER, golgi body, lysosomes?vacuoles, peroxisome and plasma membrane.
Semiautonomous organelles; mitochondria (animals) and chloroplast (plants) which provide energy for the cell.
<span>The three daily activities that affect homeostasis include;
Temperature, glucose levels, ability lymphatic system.
Homeostasis is the tendency of organisms to auto-regulate and also maintain an internal environment within a stable state. The stable condition is when the optimal functioning of organisms and dependant on many variables.
For example, fluid balance and body temperature to be kept within certain preset limits. PH of extracellular fluid, potassium, calcium ions and concentration of sodium and blood sugar levels are also variables.
It is needed to be regulated despite the diet, environment, level of activities. They are controlled by homeostatic mechanisms which when comes together maintains life.</span>
