The 21 amino acids can be arranged in many different ways. It is possible with just this small number of amino acids to create thousands of different types of proteins. Think of amino acids like they were little connecting blocks, such as legos. You have 21 of them before you. How many different ways can you arrange them? The formation of protein is similar.
Answer:
secondary structure
Explanation:
Alpha helices and beta sheets are two main structural forms in secondary structure of proteins. This structures are formed spontaneously. The next step of protein structure formation is folding into tertiary three-dimensional form.
In diseases such as CJD and kuru, protein prion is changed in structure. It is not known how degeneration of priones protein structure occurs, but it can lead to neurodegenerative diseases which can even be fatal.
Priones are also known as proteinaceous infectious particles.
Answer:
Photosystem I, however, does not act as a proton pump; instead, it uses these high-energy electrons to reduce NADP+ to NADPH. The reaction center chlorophyll of photosystem I transfers its excited electrons through a series of carriers to ferrodoxin, a small protein on the stromal side of the thylakoid membrane.
Explanation:
Weather refers to short term atmospheric conditions while climate is the weather of a specific region averaged over a long period of time. Climate change refers to long-term changes.
