Answer:
Enzymes function best at specific pH and temperatures.
Explanation:
An enzyme can be defined as a biological catalyst that typically lowers the activation energy of a biological reaction. When the activation energy of a reaction is low, the rate of the reaction would be faster. Therefore, an enzyme speeds or catalyzes the rate of a reaction by lowering its activation energy.
Also, if the conditions are not optimal for an enzyme, it limits the ability of an enzyme to bind or be joined with its substrates.
Hence, the correct statement about enzymes is that enzymes function best at specific pH and temperatures. An increase in temperature increases or speeds up the rate of a reaction while low temperature limits or reduces the rate of a reaction. The optimal temperature for enzymes in the human body is around 37 degrees celsius.
Answer: Organisms depend on other organisms and on the nonliving things in an ecosystem to meet their basic needs for food, water and protection. 3. Plants use energy from the sun to produce their own food from air and water.
Explanation:
Answer:
endothermic reaction
Explanation:
This means it cannot occur without energy (from the Sun).
Answer: 2. The rubbish is separated first by hand, then through flotation (separating plastic and paper), magnets, and an eddy current method, which pings off aluminium and other metals. A laser beam identifies each type of plastic as it passes on a conveyor belt, then a timed jet of air pushes it into the appropriate bin. There are two broad types of recycling operations: internal and external. Internal recycling is the reuse in a manufacturing process of materials that are a waste product of that process. Internal recycling is common in the metals industry, for example. 3. Repurpose Glass, Plastic and Cardboard Containers.
