Explanation:
Any compound that has carbon atoms in its chemical formula is an organic compound.
Answer: B. It decreases activation energy.
Explanation: A regular reaction has high activation energy required for the reaction to occur. Enzymes act as catalysts that decrease activation energy and speed up the reaction.
Answer: c. Transition Reaction
Explanation:
During the transition reaction, Acetyl-CoA is formed and connects the first stage of glycolysis with the Krebs Cycle (Citric Acid Cycle). In the presence of oxygen, pyruvate enters the mitochondria and is oxidized to form a compound of 2 carbon, acetate, with energy and CO2 release. During this process, the acetate binds to a coenzyme(coenzyme A (CoA)) - forming the acetyl-coenzyme A.
The 3 steps:
1. pyruvate is oxidized and forms acetate with liberation of CO2;
2. the energy released in the oxidation of pyruvate is stored in the reduction reaction of NAD+ to NADH + H+
3. The acetate molecule combines with coenzyme A to form acetyl-coenzyme A.
Acid-fast and Gram is used to visualize the structures in a membrane.
It is a differential staining procedure which is used to identify, <em>mycobacterium tuberculosis and M. leprae.</em>
Acid-fast bacteria are considered to be gram-positive in terms of their structure as, they contains peptidoglycan in its cell wall.
They stain poorly with Gram stain procedure, and appears as weak Gram-positive.
Membranes are consisted of lipid bilayer, which is doubled layer of phospholipid, glycolipid and cholesterol molecules, which contains the chains of fatty acids, and
<em>determines weather a membrane is formed into long flat sheets or round vesicles.</em>
To examine the membrane protein structure, Electron microscopy technology is used and it enables the visualization of single protein at nanometers resolution.
