During in active absorption of ions:

Options

A. Carriers are involved for both influx and efflux of ions
B. Immobile carriers with pores pumpions
C. Ions move in outer space against ecp gradients
D. Downhill transport of ions occurs

Answer

### Step-by-Step Solution:

1. **Understanding Active Absorption**: Active absorption of ions in plants involves the movement of ions from the soil into the plant roots against their concentration gradient. This process requires energy, typically in the form of ATP.

2. **Two Phases of Ion Uptake**: The absorption of mineral ions occurs in two distinct phases:
- **Phase 1 (Passive Uptake)**: This phase involves the rapid uptake of ions in the outer space (apoplast). Here, ions move along their concentration gradient without the use of energy.
- **Phase 2 (Active Uptake)**: In this phase, ions are absorbed slowly in the inner space (symplast) of the root cells. This process is active and requires energy.

3. **Mechanism of Active Transport**:
- In active transport, specialized membrane proteins (carriers) are required for the movement of ions.
- The inward movement of ions into the cells is referred to as **influx**, while the outward movement is termed **efflux**.

4. **Energy Requirement**: Active transport is characterized by the need for ATP, as it moves ions from an area of lower concentration to an area of higher concentration (uphill transport).

5. **Correct Statements**:
- Carriers are involved in both influx and efflux of ions.
- The transport during active absorption is uphill, meaning it goes against the concentration gradient.
- Ions do not move in the outer space during active absorption; they move in the inner space.

6. **Conclusion**: Based on the above points, the correct option regarding the process of active absorption of ions is that it involves carriers for both influx and efflux, and it requires energy for uphill transport.
