The types of materials that have to get in the cell, for ex. some may be too big to fit through the protein.
A better answer is:The factors that affect the rate are the size of the gradient, molecular size, charge, and lipid solubility. Sorce: http://www.innvista.com/health/anatomy/celltran.htm

Factors that can increase the rate of mediated transport include an increase in the concentration gradient of the substance being transported, an increase in the number of transport proteins available, and an increase in the efficiency of the transport proteins. Additionally, factors such as temperature and pH can also affect the rate of mediated transport.

Glucose concentration can affect active transport by influencing the rate of transport. In some cases, a higher glucose concentration can lead to an increased rate of active transport to maintain cellular homeostasis. Conversely, a lower glucose concentration may result in decreased active transport activity until a balance is restored.

Your heart rate can be affected through release in hormones, or caffeine, or exercising, or many drugs can also affect the heart rate by decreasing it.
If you want just one factor, body weight could be it. Heart rate can also affect absorption rates. Muscle to fat ration can affect absorption. Whether you have recently eaten or drank water can be a factor. Alcohol can also affect absorption rates. Pick one I guess.
No, increasing cytoplasmic pH would not decrease the rate of sucrose transport into the cell. Sucrose transport is usually driven by specific transport proteins that are not pH-dependent. However, extreme changes in pH could potentially affect the overall functioning of the cell and its transport processes.
The density dependent factor refers to the factors that affect the size or growth of a given population density. The factors also affect the mortality rate and the Birth Rate of a population. Some of the density dependent factors are disease, parasitism, availability of food and migration.
One factor that affects the rate of absorption is the molecule size. Particle size, lipid water solubility, and the degree of ionization are also three other factors that affect the rate of absorption.
