Enzymes and a single substrate use the lock-and-key mechanism.

Answer:

Enzymes and Substrate

Explanation:

The lock and Key mechanism was first postulated in 1894 by Emil Fischer. In this analogy, the lock is the enzyme which has a definite shape, with only a keyhole which fits exactly to the right key, that its then the substrate. This mechanism is used to explain the way enzymes are specific or can only degrade a certain substrate.

Alexxandr [17]

Answer:

All living things are made up of one or more cells.

Explanation:

The cell theory is a universal theory proposed by three scientists viz: Theodor Schwann, Mathias Scleiden, and Rudolf Virchow in the year 1838. These three scientists contributed to the cell theory and proposed the following:

1) All living things are composed of one or more cells

2) Cell is the basic and fundamental unit of life

3) New cells arise from pre-existing cells.

However, at an earlier date specifically 1665, an English scientist named Robert Hooke has discovered and coined the term "cells" in his published book by observing a piece of cork under a microscope. This Hooke's discovery of cells from a once living cork best supports the part of the cell theory that states that: All living things are made up of one or more cells.

Surface area is an important factor in limiting cell growth because
julia-pushkina [17]

Surface area is an important factor in limiting cell growth because

a. the cell can burst if the membrane becomes too large.

b. materials cannot enter the cell if the surface is too large.

c. the cell may become too large to take in enough food and to remove enough wastes.

d. waste products cannot leave the cell if the cell is too small.

Answer:

c. the cell may become too large to take in enough food and to remove enough wastes.

Explanation:

The exchange of substances with surroundings is done by cells by the process of diffusion. The rate of diffusion of substances requires the presence of a higher surface area than volume. As the cells become larger, their surface area is reduced with respect to the volume. Therefore, larger cells can not support the diffusion of substances in and out as required for its proper functioning. If cells are allowed to grow continuously, they will not be able to intake the requires materials such as food and to release the waste outside.
