PEROKSISOM KELAS XI KURIKULUM MERDEKA
Summary
TLDRIn this educational video, the narrator introduces peroxisomes as the 'superheroes of the cell,' highlighting their crucial role in combating harmful substances within cells. Peroxisomes are small organelles that contain enzymes like oxidase and catalase, which neutralize toxic hydrogen peroxide produced during the breakdown of fatty acids and amino acids. They are abundant in liver and kidney cells in animals and near chloroplasts and mitochondria in plant cells. The video emphasizes peroxisomes' vital functions, such as detoxifying alcohol and other harmful compounds, and their importance in cellular respiration.

- 🌿 In plants, peroxisomes are found near chloroplasts and mitochondria in leaf cells, contributing to various metabolic processes.
- 🛢️ Peroxisomes function as producers of oxidase and catalase enzymes, breaking down fatty acids into smaller molecules for cellular respiration.
- 🧪 In liver cells, peroxisomes neutralize toxins, including alcohol and other harmful compounds.
- 🍫 The script ends with a sweet note, comparing the peroxisomes' role to the flavors of chocolate and cloves, encouraging enthusiasm and sweetness.
Q & A
What is the main topic of the video script?
-The main topic of the video script is peroxisomes, which are described as the 'superheroes' of cells due to their important functions.
What are peroxisomes and where are they located?
-Peroxisomes are small cellular organelles found in cells, often referred to as microbodies. They are present in various parts of the body, including the liver and kidneys in animals, and near chloroplasts and mitochondria in plant cells.
What is the shape and structure of peroxisomes?
-Peroxisomes have a somewhat spherical shape and are enclosed by a single membrane. They contain crystalline granules.
How do peroxisomes form and increase in number?
-Peroxisomes form and grow through the fusion of proteins and lipids in the cytoplasm. Once they reach a certain size, they divide to multiply.
What enzymes do peroxisomes contain and what are their functions?
-Peroxisomes contain oxidase and catalase enzymes. Oxidase enzymes transfer hydrogen from a substrate to react with oxygen, reducing oxygen to water or hydrogen peroxide as a byproduct. Catalase enzymes convert hydrogen peroxide into water and oxygen.
Why is hydrogen peroxide produced by peroxisomes considered toxic?
-Hydrogen peroxide is considered toxic because it can damage cellular components if not properly neutralized.
What is the role of catalase enzymes in peroxisomes?
-Catalase enzymes, produced by peroxisomes, neutralize the toxic hydrogen peroxide by converting it into water and oxygen, thus protecting the cell.
What are the main functions of peroxisomes in cells?
-Peroxisomes have several functions, including the production of oxidase and catalase enzymes, breaking down fatty acids into small molecules for cellular respiration, and neutralizing toxins such as alcohol and other harmful substances in the liver.
How are peroxisomes related to the concept of superheroes?
-The script likens peroxisomes to superheroes due to their crucial role in combating harmful substances within the cell, similar to how superheroes fight against villains in a city.
What are the closing remarks of the video script?
-The video script concludes with an encouragement for viewers to stay motivated and sweet, using the metaphor of 'chocolate flavor' and 'clove bud aroma'.
Outlines
🛡️ Introduction to Peroxisomes: The Cellular Superheroes
This paragraph introduces the concept of peroxisomes as the unsung heroes within our cells. The speaker, Amalia and Siwi, use the analogy of superheroes to draw a comparison with peroxisomes, which are small organelles found in cells. They explain that peroxisomes are similar to bags containing enzymes, specifically oxidase and catalase, which play a crucial role in breaking down harmful substances within the cell. The paragraph sets the stage for a detailed discussion about the functions and importance of peroxisomes in cellular health.

Halo teman-teman kenalin aku dapur
Amalia seraviningrum absen 7 dan aku
canis ayuningrat Siwi absen 15 Kami dari
kelas 11 A1 Eh teman-teman kalian pasti
punya top up superhero favorit kan
seperti Superman spider-man Wonder Woman
Batman Hulk dan lain-lain nah sebenarnya
ini biasanya dikagumi karena bisa
melawan monster-monster berbahaya di
kota Kalian tahu nggak sih kalau di
sebuah sel juga ada superhero loh
namanya
peroksisom Apa sih itu peroksisom nah
Sini Nih Mel aku kasih tahu ya jadi
peroksisom adalah suatu organel yang
berukuran kecil nah peroksisom ini
terdapat pada sel Atau biasa kita sebut
dengan badan mikro tau nggak sih kalau
peroksisom ini bentuknya menyerupai
kantong agak bulat dan mengandung
butiran kristal yang diselu dengan
membran tunggal gimana sih peroksisom
bisa terbentuk Nah gini nih peroksisom
terbentuk dan tumbuh melalui
penggabungan protein dan lipid di dalam
sitosol kemudian setelah mencapai ukuran
tertentu akan membelah untuk
memperbanyak diri nah ini peroksiso
mengandung 2 enzim loh ya Bener banget
peroksisom mengandung enzim oksidase dan
enzim katalase enzim oksidase sendiri
berfungsi untuk memindahkan hidrogen
dari suatu substrat agar dapat bereaksi
dengan oksigen oksigen kemudian
direduksi menjadi air atau hidrogen
peroksida sebagai produk sampingan nah
hidrogen peroksida ini dihasilkan oleh
pemecahan dari asam amino dan asam lemah
di mana reaksinya adalah 2 O2 + 2H yang
menghasilkan h2o2 dan O2 Oh iya
teman-teman kalian tahu enggak sih
hidrogen peroksida yang di tadi masih
bersifat racun loh Oleh karena itu kita
memerlukan enzim katalase enzim katalase
yang dihasilkan oleh peroksisom akan
mengubah hidrogen peroksida menjadi air
dan oksigen pada hewan
peroksisom banyak ditemukan di hati dan
ginjal sedangkan pada tumbuhan
peroksisom dapat ditemukan di dekat
kloroplas dan mitokondria pada sel-sel
daun Nah itulah mengapa peroksisom
disebut sebagai superheronya sel so dari
situ dapat kita simpulkan nih kalau
peroksisom sendiri memiliki beberapa
fungsi diantaranya sebagai penghasil
enzim oksidasi dan katalase memecah asam
lemak menjadi molekul kecil sebagai
bahan bakar untuk respirasi sel dan di
dalam sel hati menetralisir racun
alkohol dan senyawa berbahaya lainnya
Oke Guys jadi segitu dulu nih pembahasan
dari kami mengenai peroksisom rasa
coklat rasa manggis semangat kamu yang
termanis
