Glucose molecules must be broken down into simpler molecules in cytoplasm before cellular respiration begins.
Answer:
<u>The enzyme's active site binds to and stabilizes the transition state, which decreases the activation energy of the reaction.</u>
Explanation:
Enzymes are complex multi-folded forms of proteins - they promote chemical reactions in biological processes.
Typically, molecules collide at random, and complex chemical reactions require the right molecular orientation and energy to react (breaking and forming bonds).
Enzymes lower energy needs by providing an alternative reaction pathway and stabilize and maintain the molecules in their intermediate forms called transition states.

Answer:</h2>
Option 3rd. anaerobic process that breaks down glucose
<h2>
Explanation:</h2>
- On observing only glycolysis it is an anaerobic process. As none of the nine steps of glycolysis involve the use of oxygen.
- After, immediate finish of glycolysis, the cell continues respiration either in anaerobic or anaerobic direction this depends upon the presence of oxygen and mitochondria.
- If oxygen and mitochondria is present the glycolysis will be broken down to produce 2 molecule of pyruvate as the end product which will be utilized in further processes(in kreb's cycle and ETS).
- In case if oxygen is absent then different types of alcohols and and acids are formed.
Result: Glycolysis does not involve oxygen and hence is a anaerobic process.
With the rain forests disappearing rapidly, it is believed that many thousands of biological species will lose their habitats and will not survive. In addition since rainforests are responsible for regulating the global carbon dioxide concentration, it is likely that rain forest loss will impact the Earth's climate.
