SUMMARY: This movie explains the biology of enzymes. Enzymes are protein catalysts that accelerate chemical reactions by lowering activation energy, playing a crucial role in processes like digestion and metabolism in all organisms. They bind to substrates at their active site, facilitating the transformation of reactants into products, and their function depends on factors like pH and temperature. However, changes in these environmental conditions can denature enzymes, reducing or destroying their activity, making them essential but sensitive players in biological systems.
My hope is that this video will catalyze lots of learning.

Enzymes LYRICS:
They're the protein catalysts in every organism
ENZYMES!
Through enzymatic action your metabolism's driven
ENZYMES!
In staphylococcus, jellyfish, tarantulas and trees,
They lower activation energy
Enzymes, in you and me now
ENZYMES!
You got 'em in your cells where they do cellular digestion,
ENZYMES!
You got 'em in your mouth and in your stomach and intestines
ENZYMES!
The thing an enzyme acts upon is called a substrate.
They fit like lock and key with complementary shape
Enzymes, speed up reaction rates
ENZYMES!
An enzyme binds its substrate at its active site
ENZYMES!
Bound together in a complex where they snuggle so tight,
ENZYMES!
New bonds will form and break due to the active site's chemistry
Reactants become products, it's the enzyme's specialty,
Product gets release enzyme repeats its action readily
ENZYMES!
Like any molecule an enzyme's shape defines its function.
ENZYMES!
Environmental change that changes shape leads to malfunction,
ENZYMES!
Every enzyme has a pH where it catalyzes best,
a pH change will set enzyme activity to rest.
Enzymes are so sensitive they're easily upset
ENZYMES!
More heat until a certain point increases their efficiency
ENZYMES!
But too much heat denatures them destroying their activity
ENZYMES!
That's why a fever running high's a dangerous situation,
All that heat can alter enzymatic conformation.
Keep it 98.6 for enzyme optimization
ENZYMES!
Enzymes in saliva will break starch into glucose
ENZYMES!
If you lack the enzyme lactase then you won't enjoy milk lactose,
ENZYMES!
Tay-sachs, galactosemia and PKU disease,
All caused by inherited enzyme deficiencies
ENZYMES, they're what everybody needs
ENZYMES!

Phonics involves matching the sounds of spoken English with individual letters or groups of letters. For example, the sound k can be spelled as c, k, ck or ch. Teaching children to blend the sounds of letters together helps them decode unfamiliar or unknown words by sounding them out.
This video gives a Brief on the Parts Of The Body and Their Functions. How they Work and much more details for you and your kids would love to Learn.
something that actually exists; reality; truth: Your fears have no basis in fact. something known to exist or to have happened: Space travel is now a fact. a truth known by actual experience or observation; something known to be true: Scientists gather facts about plant growth.

This dynamic music video describes how the Calvin cycle, also called the light-independent reactions, uses carbon dioxide from the air, enzymes, and ATP and NADPH from the light reactions to produce the three carbon sugar G3P, the building block of glucose. The three phases of the Calvin cycle: Carbon Fixation, PGA Reduction, and the Regeneration of RuBP are described in rhyme. Keywords are spelled out to reinforce science terminology. Suitable for high school and higher ed students.

Cell structure and organisation
The anatomical pathway of a reflex is called the reflex arc. It consists of an afferent (or sensory) nerve, usually one or more interneurons within the central nervous system, and an efferent (motor, secretory, or secreto-motor) nerve. Most reflexes have several synapses in the reflex arc.
A suffix is a word part added to the end of a word (for example, -ful). If you add the suffix -ful to the base word, help, the word is helpful. A prefix is a word part added to the beginning of a word or base word (for example, un-). If the prefix un- is added to helpful, the word is unhelpful.
Living and Non living Things | Science Grade 3 | Periwinkle
Hi Kids,
All things can be cl****ified between Living & Non Living Things.
Things that can breathe, eat, grow, move, have feelings, produce their young ones and die are called living things.
Things that can not breathe, eat, grow, move, have feelings, produce their young ones and die are called living things.
