Answer:

A useful model for enzyme action is the Lock and Key model.

Explanation:

The Lock and Key model or theory was first postulated by <u>Emil Fischer</u> in 1894. It is used to represent the enzyme and its specific substrate. The enzyme (lock) is specifically activated by the substrate (key) through its active site (key hole) to produce a catalyzed reaction. If the keys are too small or too big for the key hole, it will not produce any reaction.

The Double Helix model by Watson and Crick is used to represent the DNA present in an individual. This is made up of <u>two strands of DNA</u> bounded by hydrogen bonds. In between these bonds are nitrogenous bases <u>adenine (A), guanine (G), thymine (T), and cytosine (C).</u>

<u />

The Ball and Socket model represents body joints, specifically the hip and the shoulder joints. The shape of the <u>head of the joint is spherical</u> and <u>fits into a cup-like depression of the receiving bone</u>. The <u>range of motion </u>of this joint is usually <u>wide</u> and has <u>one central point</u>.

The Amino Acid Chain model, also known as polypeptides, are linked together by a <u>peptide bond</u>. A peptide bond is produced by hydrolysis. The chain usually <u>starts with the amino group and ends with the carboxyl group</u>.

1. How does our ecological footprint affect each of the spheres on Earth?
Viefleur [7K]
Lithosphere (or geosphere) describes all the rocks, minerals and molten magma found on or in the Earth

The hydrosphere describes all the water on Earth – including liquid water (oceans, etc.) and vapour (precipitation)

The atmosphere describes the layer of gases surrounding the Earth and is divided into sections (stratosphere, etc.)

The biosphere is composed of all the living organisms on the planet (including plants, animals, bacteria, etc.)


The four spheres are interconnected, so human impact on one sphere will potentially effect other spheres

The release of plastic pollution into the oceans (hydrosphere) will impact on marine life (biosphere)

The production and release of CFCs into the atmosphere will effect the impact of UV radiation on the biosphere

Explain why oxygen and glucose need to be absorbed and waste products need to be removed
AlekseyPX

Explanation:

Oxygen and nutrients from food must be absorbed into the bloodstream to be delivered to cells for respiration. Waste materials such as carbon dioxide must be removed from cells into the bloodstream. Tissues contain capillary networks to allow these exchanges to occur at a cellular level.
