The valid characteristics of enzymes from the statements provided are:
1. **Enzymes are highly selective and will only work on one type of substrate.** - This statement is generally true for many enzymes, although some enzymes can act on similar substrates.
2. **Enzymes increase biochemical reaction rates.** - This is a correct statement; enzymes act as catalysts to speed up chemical reactions.
3. **Enzymes decrease biochemical reaction rates.** - This statement is incorrect; enzymes do not decrease reaction rates.
4. **Enzymes are made of carbohydrates.** - This statement is incorrect; enzymes are not made of carbohydrates.
5. **Enzymes are proteins.** - This statement is correct; enzymes are primarily proteins.
6. **One type of enzyme can work on many different types of substrates.** - This statement can be true for some enzymes, particularly those with broader specificity, but is not a general characteristic applicable to all enzymes.
In summary, the correct statements are:
- **Enzymes increase biochemical reaction rates.**
- **Enzymes are proteins.**
- The first statement about high selectivity is somewhat true but not universally applicable, and the last statement can be true for some enzymes but not for all.
