Why are cells limited in size?

Biology
1 answer:
seropon [69]3 years ago
5 0
Cell is limited in size for many reasons. Cells wouldn't be respire effectively if it were too large, because the surface area to the volume ratio would be too small.
The other thing is that if the cell were too large, it would be difficult for it to move nutrients and waste products in and out of the cell. So, cells are limited in size.

madam [21]

The question is incomplete, the complete question is;

Census data show that the human population

doubled from 2.65 billion in 1953 to 5.3 billion

in 1990. If it continues to double at this rate,

the human population could reach 10 billion

by the year 2020. Which BEST explains how

this rate of human growth can harm the

environment on which humans depend?

A. by gradually making up more available energy

B. by using resources faster than they can be

replaced

C. by changing how matter cycles through an

ecosystem

D. by increasing the variety of ecosystems that are

Answer:

by using resources faster than they can be

replaced

Explanation:

As population of the world continues to grow, there is greater demands for resources which are obtained from the environment such as crude oil for energy, solid minerals for various applications, wood for furniture etc.

Demand for these materials increase exponentially as population increases thus they are extracted at a faster rate than nature can replace them. This will eventually harm the environment on which humans depend as population increases.

What will happen when the cell has produced more products than it has enzymes?
Gemiola [76]

Answer: If you have an excess of enzyme but not enough substrate, the reaction will be limited by the substrate availability.

Explanation: Once you add more hydrogen peroxide to the solution, the reaction rate will increase as more substrate molecules can collide with the enzyme, forming more product.

Drag the labels onto the equation to identify the inputs and outputs of cellular respiration.
marysya [2.9K]
<span>The inputs are also called reactants. In Cellular respiration, there are certain inputs in the form of glucose and oxygen. The outputs, generally known as the products, are water, carbon dioxide, and ATP molecules.

The general equation used to represent the inputs and outputs of cellular respiration is:

Glucose + Oxygen → Carbon Dioxide + Water + ATP + Heat + Energy

C₆H₁₂O₆ +6O₂ → 6CO₂ + 6H₂O + Energy (ATP+ Heat)</span>
