Semester 1 exam

Forms the brain, spinal-cord and nerves

• Transports oxygen via haemoglobin - HbO2

Determines what enters/exits the cell

When two or more substances react to form one

Involved in sellular production

Connect the cell membrane to the nuclear membrane and provide a surface for chemical reactions to occur

Attack bacteria with enzymes

Stores nutrients/dutoplasmic substances, secretory products and pigment granules nonliving

Lock and key and induced fit

Breaking down molecules into small molecules

Releases energy for the cells through respiration

The concentration of enzymes and substrate. A chemical reaction occurs when an enzyme and the substrate collide. The more molecules present the greater the chance of reaction

30 to 38

Something that may be required for enzyme function. these bind to the enzyme to temporarily activate it. Could be ions, vitamins

Where amino acids join to make proteins

Skeletal, smooth, cardiac.

Packages materials for Endocytosos & exocytosis

Anaerobic. Pyruvate is completely broken down into six carbon dioxide molecules. Takes place in the mitochondria matrix. Produces two ATP molecules

Electrons get transported from molecule to molecule creating a series of chemical reactions. Water is a product of these reactions. Makes 32 to 34 ATP molecules by adding one phosphate to each ADP molecule.

Carry oxygen and nutrients to the cells around the body, removes waste from the body, bring oxygen into body from lungs, circulate blood to body, maintain body temp and white blood cells fat infection

I phosphate molecules is stripped from ATP to make ADP again. This releases energy and enables biological work.

The fluid in the cytoplasm 75 to 90% water

– Retired organelles – Carbon dioxide – Urea – through urine – made from excess protein – Water – Salts

A tissue is a group of cells that are similar in structure that work together to carry out a particular task.
