Answer:
Explanation: They both require the binding of Ligand.
Differences:
Intracellular receptor is located in cytosol. It can be found in the nucleus. It leads to slower responses related to gene transcription. They are steroids. Ligands are lipophilic, small, uncharged; diffuse through membrane and bind to receptor.
Plasma membrane receptor-
The Ligands are hydrophobic and don't have to be small and uncharged; bind only to membrane receptor. Extracellular signaling molecule binds to cell membrane receptor and triggers rapid cellular response (protein hormone)
The answer is; C
It is a woody plant with a flexible stem that can grow extremely long. Its stem cannot stand vertically on its own hence uses other trees for support and climbs up the canopy for good sunlight. They are common plants in rainforests and play a significant role in the ecosystems. They provide support for weaker trees from strong winds and provide bridges for arboreal animals such as monkeys.
C) is definitely the bacterium!
A) look like a paramecium with it's flagela and vacuole
B) is a plant cell with chloroplasts
D) could be an animal cell, plant, or fungal since it has a nucleus
**remember: bacteria lack ALL membrane bound organelles: nucleus, mitochondria, chloroplasts, E.R.!!

Answer:
Enzymes catalyze specific reactions.
Explanation:
Enzymes are known as both biological catalysts and proteins. It is a substance that acts as a biological catalyst in an organism. The biological processes are chemical reactions, most are regulated by the help of enzymes that occur within all living organisms.
Enzymes are the highly selective catalyst in nature means each enzyme only helps to speed up a specific reaction. Catalysts help to lower the activation energy for reactions. So, if lower the activation energy for a reaction, the faster the rate of reaction.
