Please note:Lysosome dyes such asNeutral Redrequire an acidic environment for this organelle and work best in live cells. One tip, is to first add the lysosome dye before subsequently fixing your cells, thus enabling the addition of protein-specific antibodies afterward. 4. Mitochondria Mitochondria...
The site of aerobic respiration in the cell is what organelle? Identify the principal organelle or cell components described here: a. helps organize spindle fibers during cell division (mitosis) b. the major site of energy production in the cell c. a system of membranous tubules in the cytopla...
Photosynthesis is the process in which plants capture light from the sun and transform it into energy. Break down the photosynthesis reaction, learn how to test the reaction rate for photosynthesis in a biology lab, and analyze the results. R...
One of the cell's main functions is to provide energy to living organisms by producing energy molecules. These molecules are produced through the digestion and absorption of nutrients in the food in which a series of chemical reactions transform the food that is eaten by an organism into energy...
1. 1. Communication is so essential to the living state at all its different levels of organization, from the cell organelle to the population, that in my opinion life could be defined as follows: Death ensues when the ability to communicate at the highest level of organization of the ...
Visualizing the interior of organelles helps us to understand their molecular mechanisms and study cell abnormalities.Firstly, what is an organelle? Organelles are small subcellular structures located in the cytoplasm of eukaryotic and prokaryotic cells, and in more complex eukaryotic cells, organelles ...
1 The figure below is an electron micrograph of a section of a cell.What is the function of the organelle shown in the figure? B A control movement of substances into the cell B package substances for secretion C release of energy from glucose D synthesis of lipids and proteins 相关知识...
That "powering" molecule, which like glucose is active in all cells, isATP, oradenosine triphosphate, a nucleotide often called "the energy currency of cells." Which molecule should you think of, then, when you ask yourself, "What molecule is the fuel for all cells?" Is it glucose or ...
One example is the mitochondrion— commonly known as the cell's "power plant" — which is the organelle that holds and maintains the machinery involved in energy-producing chemical reactions (Figure 3). Figure 2: The composition of a bacterial cell Most of a cell is water (70%). The ...
Atmospheric nitrogen (N2) is very stable, so it takes an incredible amount of energy to convert it to a different form. Lightning Strikes If you've ever wondered why your outdoor plants seem happier after a rain than they do when you turn a sprinkler on them, there's a reason for ...
