transport allows the organism to receive and send molecules without exerting energy. What if you could get things your chores done and not do anything but sit on the couch and watch your favorite show? That is what this transport does! Just like humans, cells need to bring in oxygen and release carbon dioxide. We also don’t have to put in that much energy into bringing oxygen into our bodies just like cells! According to biology junction, “small molecules like water, oxygen, and carbon dioxide…

enzymes in our saliva broke down the starch molecules, which caused them to rearrange and create a new product: glucose. My second piece of evidence comes from Reading 4.1, where we collected the evidence that when starch is broken down and mixed with water, it creates glucose. This reading also provided us with the information that saliva is made with water, salts, mucus, antigerm compounds, mouth cells, and…

After letting the potatoes sit for a few days. The potato in the freshwater solution was soft and sticky, it could be easily squished it also had a bad scent because the potato had gone bad. However, the potato in the saltwater solution was firm and had become more narrow than before, it did not have a scent like the freshwater potato did. The solution that caused the potato to change the most in circumference and mass, was the saltwater solution. In the data table the potato in the fresh water…

living organic cell. Biological molecules are put under groups based on the way they behave and the similarities they share. There are four main types of macromolecules, namely proteins, nucleic acids, fats and membrane lipids and carbohydrates (which include monosaccharides and polysaccharides). (Alberts, Walter, Bray, Hopkin, Johnson, & Lewis, 2015) There are four smaller organic molecule families which are the primary components of macromolecules. These four molecules are the sugars,…

called facilitated diffusion. Facilitated diffusion is the spontaneous movement of a solute that goes into the channel protein. A solute goes into the pore of the channel, then the channel helps diffusion process and does not require energy. The molecule is released in the far side of the…

fast the molecules in an object are moving. The faster the molecules in an object are moving, the more heated the object becomes. Magnetism is when an object has a magnetic force, field, or a pull on another object. Temperature affects the strength of magnetism. The property of systems that ultimately determines the direction of heat energy flow when objects are put into contact with each other is known…

different molecules since the Carbons in the Lipids have a higher oxidation number, which leads to a higher energy density than the lower oxidation numbers of Carbohydrates(2). The energy density of Lipids versus Carbohydrates ultimately boils down to Redox Reactions and the movement of electrons in reduction and oxidation reactions between organic molecules. For example, the ten Carbon atoms which are connected to two Hydrogens and two Carbons in the large Lipid chain for the molecule known…

production of two ATP molecules. The pyruvate product of glycolysis can be used in either anaerobic respiration when no oxygen is available or in aerobic respiration within the TCA cycle. A glucose molecule is energized by a phosphate from ATP, forming glucose-6-phosphate. It is then altered to form fructose-6-phosphate. Using a second ATP molecule a second phosphate is added to the fructose which becomes fructose-1,6-biophosphate. This is then split into two 3-carbon molecules with one…

it create ATP molecules which is energy for it to live. In the process of photosynthesis there are six molecules of water, and of carbon dioxide react in the presence of chlorophyll and in sunlight to make 2 molecules of sugar, and six molecules of oxygen, which looks like 6H2O +6CO2- C6H12O6+6C2. There are two stages of photosynthesis, a light stage and a dark stage. The light stage was described above however, the dark stage is when the ATP and NADPH is stored, and these molecules were…

II.I How it is use? Muscle contraction requires the use of ATP molecules. Indeed, muscle cells are composed of contractile elements: sarcomeres. Muscle contraction is due to the slippage of myosin fibers on the actin fibers. For this, the head of the myosin binds to the troponin site of the actin filament. Then, an ATP molecule will bind to myosin to separate actin and myosin and thus allow its attachment to the neighboring troponin site due to hydrolysis of ATP in ADP + Pi. This creates a…
