Le radiazioni luminose utilizzate dagli organismi fotosintetici hanno diverse lunghezze d'onda comprese tra i 280 nanometri (luce viola) e i 750 nanometri (luce rossa). Le molecole che sono in grado di assorbire la luce sono i pigmenti.

La demolizione del glucosio prevede: la glicolisi, che avviene nel citosol, e la respirazione cellulare, che si svolge nei mitocondri in presenza di ossigeno; in assenza di ossigeno, dopo la glicolisi si ha il processo di fermentazione.

Le cellule autotrofe sono in grado di sentitizzare le proprie molecole organiche grazie all'energia ricavata da reazioni inorganiche (cellule chemiosintetiche) o dalla luce solare ( cellule fotosintetiche).

Le reazioni tramite cui gli organismi chemiosintetici assemblano le molecole organiche prendono il nome di fissazione del carbonio; la molecola base si ottiene è il glucosio.

Un'ossidazione è la rimozioni di elletroni, mentre la riduzione, l'inverso dell'ossidazione, è l'acquisizione di eletroni; le 2 reazioni hanno sempre luogo contemporaneamente.

Due importanti processi di fermentazione sono la fermentazione alcolica, a opera di certi lieviti, e la fermentazione lattica, che avviene nelle cellule muscolari; entrambe hanno un guadagno energetico limitato.

L'anabolismo è l'insieme dei processi mediante cui le cellule assemblano le proprie molecole organiche; quello mediante cui tali molecole vengono demolite per creare energia è detto catabolismo.

Se una reazione avviene grazie a un apporto di energia proviìeniente dall'esterno è detta endoergonica se, nel corso del suo svolgimento, cede energia all'ambiente.

La parte della molecola enzimatica in cui avvengono le reazioni catalizzate dall'enzima è detta sito attivo; la molecola, invece, su cui agisce un enzima è chiamata substrato.

Molti enzimi richiedono la presenza di determinate sostanze non proteiche, chiamate cofattori, per poter svolgere le loro funzioni; tra essi ci sono i coenzimi.

Una caratteristica degli enzimi è quella di lavorare in serie; ciascuno catalizza un piccolo passaggio di una serie ordinata di reazioni detta, nel suo complesso, sequenza biochimica.

Quando un gruppo fosfato terminale si stacca, per mezzo degli enzimi ATPasi, la molecola di ATP si trasforma in ADP liberando energia.

Il gruppo fosfato terminale non viene rimossa ma trasferita, l'aggiunta viene chiamata fosforilazione.

Be Brave and Take Risks: You need to have faith in yourself. Be brave and take risks. You don't have to have it all figured out to move forward.

I loved reading Grimm's fairy tales and Hans Christian Andersen, and I loved to dream about other worlds and other lives. Maybe that has something to do with having an incomplete family, being an only child. All I know is I loved to pretend, and all that was in tandem with my wanting to be an actress.

No one's policing their own minds more than an author. You spend a lot of time in your own head analysing what you think about things, and a philosophy comes.

If you're a white person in the wrong neighborhood, you're an underdog.

Music is my thing. It's my thing; it's what I love. It's what I do. It's football to me; it's Christmas to me; religion to me; poetry to me.

I like going everywhere. And I love starting new things.

Like a lot of films at the end of 2008, they hit a wall with financing, which is why I moved back onto 'Stone.' In doing so, I had to let go of 'The Beautiful and the Damned,' to at least give them an opportunity to move forward with somebody else.

One of the things I do is try to get a positive message out there in the local schools and tell my story. I also do a lot of faith-based speaking, sharing my story and testimony, to help show what God has done in my life and what he can do in others' lives.

I was 35 when I started taking classes at Ohio University. After I got my degree, I kept working at the mill. When I was 45, I decided I was going to try to learn how to write short stories.

It's 5 P.M. at the office. Working fast, you've finished your tasks for the day and want to go home. But none of your colleagues have left yet, so you stay another hour or two, surfing the Web and reading your e-mails again, so you don't come off as a slacker. It's an unfortunate reality that efficiency often goes unrewarded in the workplace.

There are some great women's roles in television... so much more interesting than what I was reading in film scripts.

The Bible tells us that we're supposed to leave an inheritance for children.

As I get older, I realize all I've done is sing and act and hone those skills.

Democracy may mean something more than a theoretically absolute popular government, but it assuredly cannot mean anything less.

Healthcare providers will compete to offer the best record of patient safety at the lowest prices. Hospitals and patients will benefit from having accurate information about areas of excellence and areas that must be improved.

Obviously, a theatrical masterpiece needs more than a plot; many television shows are nothing but plot, and it is doubtful that they will stand the test of time. But I also don't think that making fun of plot or acting like we're all somehow 'above' structure is such a good idea.

People just wanna talk. They wanna create negative things about you and your life and make up things. You can't let them affect you!

I went a long way to play in Manchester United, so nothing will prevent me from achieving my dream.

I claim there ain't Another Saint As great as Valentine.

Sanctions historically are quite counterproductive in the sense that if you impose sanctions on your enemy, it tends to strengthen your enemy.

If you do not tell the truth about yourself, you cannot tell it about other people.

Two young actresses I admire are Emma Stone and Emma Watson, because they are intelligent, talented actresses and have a great sense of humor. They have learned to balance what they love in life - acting, school and everything else.

I'm competitive with myself, and that goes hand in hand with how I present myself. I'm not only trying to put one foot in front of the other, I'm trying to put my best foot forward.

We have a choice - we can both think and feel, using our heads and our hearts.
