Semester A Unit 2 Lesson 1: biochemistry unit introduction Flashcards
What does biochemistry
the study of matter that makes up living things.
What is chemistry
Chemistry is the study of the substances that make up matter.
Food science is a feild of study that requires what level of knowledge?
Food science is a field of study that requires a college degree and courses in biology, chemistry, biochemistry, and microbiology.
What do people who study food science become?
People who study food science may become public health researchers who track food-borne pathogens. Or, they may want to work to develop new or improve foods for companies in the food industry.
What is all matter made up of?
All matter is made up of smaller particles called atoms.
How many atoms are in an element?
An element consists of one type of atom.
How many atoms does the element carbon have?
The element carbon is made up of only carbon atoms.
When atoms combine what do they form?
Atoms combine to form molecules.
How many protein molecules are in a single cell?
Recent research indicates that a single cell holds over 40 million protein molecules. These protein molecules perform many of the functions of the cell.
What do all organisms have to do to survie?
all organisms need to take in matter from the environment to survive. During photosynthesis, plants use light, carbon dioxide, and water molecules from the environment to produce glucose and oxygen. Humans and other animals cannot produce their own food, so they need to eat plants, animals, or other organisms. When food is eaten, the body breaks down the molecules in food and uses the matter within these molecules to make new molecules that the body needs for growth, repair, and other life functions.
How do plants absorb matter?
During photosynthesis, plants use light, carbon dioxide, and water molecules from the environment to produce glucose and oxygen.
What happens when food is eaten?
When food is eaten, the body breaks down the molecules in food and uses the matter within these molecules to make new molecules that the body needs for growth, repair, and other life functions.
What is the smallest unit of matter?
The atom is the smallest unit of matter.
What are phosphlipids?
Phospholipids are molecules that make up cell membranes.
What are known as the building blocks of life?
cells
