The energy pyramid describes decomposers compared to energy lost as heat. Primary producers start at 100% and it decreases to 10% at primary consumers, 1% at secondary, .1% at third level, and .01% at apex.
The biomass pyramid describes the total mass of an organism and as a biomass moves up, the overall mass is losing volume. This means it decreases as it moves from the bottom to the top.
The genotype for both parents is Br. if using B= black and r = red
The answer is b because it is negative on our world
If the researchers replaced the bacterial proton pump with a proton pump that was activated only by atp then less ATP would be produced when the light is on because no proton gradient would be available to produce ATP.
<h3>What is
proton gradient ?</h3>
Two quinol (4H+4e) oxidations at the Qo site result in the formation of one quinol (2H+2e) at the Qi site, creating a proton gradient (in total six protons are translocated: two protons reduce quinone to quinol and four protons are released from two ubiquinol molecules).
For the ETC to continue functioning, the energy trapped in the electrochemical gradient of protons across the inner mitochondrial membrane must also be released in some manner. ATP is created using the energy in the proton electrochemical gradient.
Chemiosmotic coupling is the process by which ATP synthesis is coupled to the electrochemical gradient of H+ across the inner mitochondrial membrane.
Peter Mitchell, who in 1961 made the initial suggestion, was given the Nobel Prize for his efforts in 1978.

Answer:
el acetil-CoA necesario para la síntesis de colesterol puede provenir de la vía glucolítica
Explanation:
El colesterol es fundamental para la formación de las membranas celulares, actuando como mediador del grado de fluidez en las membranas; además, esta molécula actúa como precursor de hormonas esteroideas y ácidos biliares. La sintesís de colesterol empieza con la condensación de acetil-CoA y acetacetil-CoA:
Acetil-CoA + Acetacetil-CoA + H2O >>> 3-hidroxi-3-metil-glutaril-CoA
Ahora bien, el acetil-CoA para este proceso puede ser producido por la degradación hasta piruvato del excedente de glúcidos mediante de la vía glucolítica. Este reacción se produce dentro de la mitocondria, donde el piruvato produce acetil-CoA.
