Proteins, Aerobic Respiration, Anaerobic Respiration Flashcards
WHAT ARE PROTEINS MADE UP OFF
Long chains of DIFFERENT amino acids
4 TYPES OF PROTEINS
• Structural
E.g. Collagen
• hormone
E.g. Insulin
• Carrier molecule
E.g. Haemoglobin
• enzyme
E.g. Amylase
WHAT IS A CATALYST
A substance that increases the rate of reaction without itself undergoing any permanent chemical change
MUSCLES ARE MADE OF PROTEINS
true or false
TRUE
AMINO ACIDS BEND AND FOLD EXTENSIVELY FORMING A SPECIFIC 3 DIMENSIONAL SHAPE.
True or false
TRUE
this shape is then help together by chemical bonds
WHEN IS AEROBIC RESPIRATION USED
when the body is able to supply the cells with oxygen and glucose needed, it carries out aerobic respiration
CHEMICAL REACTIONS INSIDE CELLS ARE CONTROLLED BY ENZYMES
true or false
TRUE
WHAT DOES RESPIRATION DO
Respiration provides energy needed for life processes
ENERGY IS NEEDED FOR LIFE PROCESSES SUCH AS (3)
- protein synthesis
- muscle contraction
- control of body temperature in mammals
AEROBIC RESPIRATION WORD EQUATION
Glucose + oxygen = carbon dioxide
+ water
SYMBOL EQUATION FOR AEROBIC RESPIRATION
C(6)H(12)O(6) + 6O(2)
(666)
6CO(2) + 6H(2)O
WHAT HAPPENS TO OUR
Breathing rate
AFTER WE EXERCISE
breathing rate increases to get more oxygen into your body, and to release more carbon dioxide form your body
WHAT HAPPENS TO OUR
heart rate
AFTER WE EXERCISE
It increases so the body can pump oxygen around quickly
MUSCLE CELLS RESPIRE MORE DURING EXERCISE
true or false
TRUE
Oxygen and glucose must be delivered quicker and waste carbon must be removed quicker
MUSCLES STORE GLUCOSE AS GLYCOGEN WHICH CAN BE EXERTED BACK INTO GLUCOSE FOR USE DURING EXERCISE
