Viruses arent able to respond to stimuli when outside of a host cell because outside host cells, viruses are dormant and sometimes even considered dead. Only when a virus starts reproducing in a cell can it weakly respond to stimuli. :))
Answer:
Option C. Glucose.
Explanation:
Glucose is produced when carbondioxode is entered
in the plant body from the surrounding air through stomata and water is absorbed by the plant from soil through roots in the presence of sunlight. This process is called photosynthesis which occurs in plants for the preparation of food materials. Here food refers to glucose molecules. Oxygen is also produced in this process.
I feel dead……………zzzzzzzzzz
Answer:
Animal cells (including humans ofcourse), heterotrophs, derive their energy from coupled oxidation-reduction reactions. Glucose is a primary fuel for heterotrophs. Energy derived from glucose is stored in the form of high-energy phosphate bonds in ATP, or other nucleotide triphosphates, and as energy-rich hydrogen atoms associated with the co-enzymes NADP and NAD .
Glucose is unable to diffuse across the cell membrane without the assistance of transporter proteins. At least 13 hexose transporter proteins with different functions have been identified. Some hexose transporters allow glucose to flow passively from high to low concentration without requiring the expenditure of cell energy. Those that move glucose against its concentration gradient consume energy, generally in the form of ATP.
D-Glucose is the natural form used by animal cells.
So yes it is present inside human cells .
