First off, quick definition: <u>molecules</u> = a group of atoms/elements (not just a single element like "O" or "H", so all of these are molecules in this problem and we can instantly rule out answer choice D).
In this problem, your given chemical equation. The <u>reactants</u> (starting materials) are on the left side of the arrow (→). The <u>products</u> (finishing materials) are on the right side of the arrow. Sometimes special reactants (like enzymes i.e catalase) are written over top of the arrow instead of on the left side of the arrow.
Anyways, we can read this reaction like this:
- Start out with 2 molecules of 
- Add Catalase
- End up with 2 molecules of 
(water) and 1 molecule of 
(oxygen)
Therefore, catalase must helped break down the bigger molecules into the small "building block" molecules of and .
***SEE PIC FOR VISUAL...if you want. This always helped me. You can see easier that the bigger molecules are being broken down into multiple smaller ones***

<em><u>Correct Answer:</u></em><em>
B</em></h2>
Answer:
The given statement is true.
Explanation:
- The chemical structure of triglycerides includes:
- A glycerol molecule attached with ester bonds to,
- Three fatty acid chains.
- Among all the bio-molecules available in the cells, triglycerides store the maximum energy, due to the presence of long carbon chains with single (saturated) or double/triple (unsaturated) bonds.
- One gram of triglyceride can store about 38 kJ of energy which is double the amount that can be stored in carbohydrates.
- During metabolism, these molecules are hydrolysed by enzymes called lipases, those are secreted by the pancreas, into fatty acids, mono- and di-glycerides, by the process of lipolysis.
- Bile in the intestine further promotes the action of lipases.
- These digested components are absorbed into the duodenum through the enterocyte cells where they associate with proteins and cholesterol to form chylomicrons.
- These chylomicrons are released into the lymphatic system and from there cells of various organs can absorb them for storage or hydrolysis.
- The triglycerides are used in the cells for energy by hydrolysing them using cell specific lipases to fatty acid and glycerol.
- The glycerol is used to produce glucose and the fatty acids are further hydrolysed or converted to ketone from which amino acids can be formed.
<span>There are many types of algae. Some of which are brown algae or the Phaeophyta/Phaeophytes,the green algae which is also known as the Chlorophytes, and the Chrysophytes or the golden algae. Among these algae, only the Chrysophytes shows distinct alternation of generations or metagenesis.</span>
Explanation:
Lipids is incorrectly matched with carbohydrates. Fatty acids and glycerol make up lipids instead.
