George Emil Palade Quotes

Life needs a membrane to contain itself so it can replicate and mutate.

A living cell requires energy not only for all its functions, but also for the maintenance of its structure.

In basic research, the use of the electron microscope has revealed to us the complex universe of the cell, the basic unit of life.

I became aware of the very complex internal organization in a cell from the basic science classes, and it made me think about how all that could work. It seemed like a great mystery, especially how organelles in the cell can be arranged in three dimensions, and how thousands of proteins could find their way to the right location in the cells.

By 'life,' we mean a thing that can nourish itself and grow and decay.

I think you can say that life is a system in which proteins and nucleic acids interact in ways that allow the structure to grow and reproduce. It's that growth and reproduction, the ability to make more of yourself, that's important.

Physiology is the science which treats of the properties of organic bodies, animal and vegetable, of the phenomena they present, and of the laws which govern their actions. Inorganic substances are the objects of other sciences, - physics and chemistry.

Proteins are the machinery of living tissue that builds the structures and carries out the chemical reactions necessary for life.

Biochemistry is the science of life. All our life processes - walking, talking, moving, feeding - are essentially chemical reactions. So biochemistry is actually the chemistry of life, and it's supremely interesting.

The living cell almost always contains, locked in its interior, the visible or invisible products of its physiological activity or its nourishment.

Life is the division of human cells, a process which begins at conception.

The properties which differentiate living matter from any kind of inorganic imitation may be instinctively felt, but can hardly be formulated without expert knowledge.

The cell is a city of production centres, each part working away like mad, and it's co-ordinated. Six trillion cells in a body - you can't help but be moved.

We are seeing the cells of plants and animals more and more clearly as chemical factories, where the various products are manufactured in separate workshops.

In reality, a cell is a biological mini-me compared to the human body. A cell has every biological system that you have.

Our cells engage in protein production, and many of those proteins are enzymes responsible for the chemistry of life.

Hormones get no respect. We think of them as the elusive chemicals that make us a bit moody, but these magical little molecules do so much more.

A cell is a complex structure, with its investing membrane, nucleus, and nucleolus.

I was driven completely by a desire to understand how cells worked.

The nucleic acids have considerable biological importance because of their role in cell growth and in the transmission of hereditary characters.

Trying to understand fundamental processes that take place as organisms develop and how their various cells interact with one another - one can see what happens with those cells by asking questions about the fundamentals of biology.

The human body is essentially something other than an animal organism.

Cells will die in minutes to days if they lack their genetic information system. They will not evolve, they will not replicate, and they will not live.

The egg of every species of animal or plant carries a definite number of bodies called chromosomes. The sperm carries the same number. Consequently, when the sperm unites with the egg, the fertilized egg will contain the double number of chromosomes.

When we think of what is necessary for the phenomenon that we call life, we think of compartmentalization, keeping the molecules which are important for life in a membrane, isolated from the rest of the environment, but yet, in an environment in which they actually could originate together.
