Myosin and actin protein filaments attach to each other . Calcium ions release into myofibrilles . Myosin filaments pull on the actin filaments
This process is called Facilitated diffusion. because the protein channels must help the substance get into the cell based on fitting. It's important to regulating what comes in and goes out.
Answer:
2
Explanation:
H2O = 2 hydrogen + 1 oxygen
Marijuana is only not legalized to incarcerate minorities, predominantly Mexican/Black people. At the turn of the 20th century, cannabis, as it was then commonly known in the United States was a little-used drug among Americans. With the start of the Mexican Revolution in 1910, many Mexicans began moving to the United States, and they brought with them the tradition of smoking marijuana. Anslinger (1930s Harry J. Anslinger, head of the Federal Bureau of Narcotics) sought a federal ban on the drug, and to this end he initiated a high-profile campaign that relied heavily on racism. Anslinger claimed that the majority of pot smokers were minorities, including African Americans, and that marijuana had a negative effect on these “degenerate races,” such as inducing violence or causing insanity. Quite ironically Marijuana is less harmful than alcohol, and that adults should have a right to use it if they wish. Marijuana could also help with medical complications such as Anxiety and “chronic pain that plagues millions of Americans, especially as they age. Part of its allure is that it is clearly safer than opiates (it is impossible to overdose on and far less addictive) and it can take the place of NSAIDs such as Advil or Aleve, if people can’t take them due to problems with their kidneys or ulcers or GERD” said Harvard University.
The answer is; active transport in small intestines and passive transport in blood cells
In passive transport, no energy is required to transport the glucose molecules because they spon6tanosuely move down their concenntrati0n gradient. The transport protein in the blood cell membrane only enables the molecule to pass across the hydrophobic layer of lipid in the membrane and into the cell.
In active transport, energy is required in the transportation of glucose against their concentration gradient (glucose is highly concentrated in the lumen of the intestines than in the bloodstream). Sodium/Potassium (Na+/K+) pumps play a significant role in the transport of glucose. When sodium diffuses back into the cells, they drag along glucose molecules with them across the sodium-glucose transporter protein.
